Top 6 Biggest Bitcoin Hacks Ever - CoinSutra

Diversifying your 2018 investment portfolio with high risk and low risk coins

After months of thorough research I put together the best portfolio in crypto in my opinion. The portfolio is divided into high risk, high return (100x) bets, medium risk medium return (10x) and low risk, low return (3x-10x).
If you want to put $30k into crypto, here is what I recommend to get the best outcome.

1. $10k into high risk high return coins XSPEC, SUMO, ECC, ODN, BNTY, SNOV.

XSPEC and SUMO are 2 are privacy coins that are currently at a tiny market cap of $9M and $4M. 3 months ago, when Bitcoin was at its All-time-high, their market caps were at $113M and $32M respectively. In case, Bitcoin goes up to its ATH of $20,000 again, those 2 coins will go back to their ATH again, too. The thing is, altcoins behave the same as Bitcoin, only that they move at a much higher percentage than the big one, Bitcoin. For example, if Bitcoin goes up 30%, all small altcoins with a market cap under $10M, such as XSPEC, will go up by around 90%.
Privacy coins such as Monero are one of the most sought after cryptocurrencies currently and experts expect a big rise of privacy coins 2018. XSPEC and SUMO are very similar in technology to Monero, maybe even superior though their market cap is 100 times less, since they are less than 1 year old.
ODN, BNTY and SNOV are the small market cap coins with the biggest expected commercial use of the blockchain as a messenger (ODN), Bug-Bounty platform (BNTY), lead-generation (SNOV) and decentralized file storage (ECC). There already exists a file storage coin Siacoin at 20x the market cap of ECC without much reason for the big gap due to ECC's solid technology.
There are a also a few more very small cap coins that I considered, such as DNA in the medical field, and ELIX, though I found their potential less convincing than that of the above mentioned cryptocurrencies.

2. $15k into medium risk medium return (10x) coins, COSS, POE, PRL, DBC, ENJ.

COSS is the platform coin of the COSS crypto exchange. It is an exchange like Binance, but it is seen as one of the best small and innovative exchanges that currently exist. They will also release their mainnet in a few weeks, which will give them another boost.
DBC is one of the few cryptos that make use of artificial intelligence. They have a very strong team and are one of the few cryptos in the AI space.
ENJ, this is probably the coin with the most real-world usage of all cryptos. There are already a few gaming coins out there, such as FUN and MobileGo, however, ENJ is one of the few that real numbers behind them.
With more than 18 million users and 250,000 gaming-based communities, **Enjin* is among the world’s largest social gaming platforms. Recently, Enjin launched its cryptocurrency—Enjin coin—an Ethereum-based token to be used on a platform that allows for the development, distribution, organization, and trading of virtual goods.
As of 2 weeks ago, they closed a partnerships with one of the biggest games, Minecraft and will be used as a currency within Minecraft.
POE is a decentralized platform that allows publishers to license, identify, and monetize digital content such as blog posts, news articles, YouTube videos, audio/music, e-books and more. Here is a very good article about them. https://www.reddit.com/CryptoCurrency/comments/7oubqm/my_thoughts_on_poe_and_why_2018_could_be_big_fo
PRL is a very interesting one. It gives website owners the ability to generate revenue from their visitors without having to feature pushy advertising by storing encrypted data, but by mining PRL. https://www.reddit.com/CryptoCurrency/comments/7t4o95/oyster_prl_is_going_to_change_the_internet_heres/

3. $5K into low risk, low return (3x-10x) coins Bitcoin, Ether, Nano, VEN, IOTA, BNB.

Ok let's get to the juggernauts. If you are rather conservative, Bitcoin and Ethereum will make you a good profit in the coming years, maybe even 10x if you're lucky. However, if Bitcoin goes 10x, all smaller altcoins go 100x, so it is worth diversifying a little.
The thing is, Bitcoin's technology is very outdated. It cannot handle more than 20 transactions per second, it uses as much energy as a small country and with increased usage their fees will skyrocket again. This is the problem of 1st generation blockchains. Bitcoin cash has the same problem and while they can handle double as many transactions as Bitcoin due to their block size being twice as big, it's only a drop in the ocean, since they need to be able to handle 1000x as many transactions as now if they want to be used as a payment processor.
A good comparison to get an idea for transaction volume is VISA, which handles a couple of thousand transactions per second and is able to handle 60,000 transactions /second at peak times. A crypto payment processor needs to be as good as that. However, 60,000 transactions (tx)/second isn’t even a good benchmark. It’s the same as comparing the number of faxes sent with the number of emails sent. If you want to surpass old technology, you should go for 100x the amount of usage. More on that in the paragraph about IOTA.
I personally won't put anything in Bitcoin and Ether, because they are rather outdated cryptocurrencies now and they can only grow another 10x maximum within the next year or 2, while there are many other coins that can grow 100x or more within the same time frame.
Now we have VeChain, a supply chain cryptotechnology. VeChain is already very mature and it is the most popular and loved altcoin next to Nano. It is a safe bet.
Let’s get to IOTA. They have built a very exciting new technology. They are not using a blockchain, but a Tangle. It is a 3rd generation blockchain that has zero fees and instant transaction times. IOTA’s real world application is in IoT, Internet of Things. They are using their tangle to connect to and make transactions between millions of small devices, be it temperature regulator, heating, car, lights. Now you can see why a high transaction volume is so important, because these devices communicate multiple times every second with one another through these transactions. It is estimated that in 10 years time, 80 billion IoT devices will exist worldwide, which probably create 80 billion tx/second or more. IOTA is designed to do exactly that. Bitcoin can only do 10 tx/second. Currently, 8 billion IoT devices are connected to the internet.
However, IOTA has not been stress tested at this volume. It is not yet clear that transactions will remain instant at this volume, nor is it clear if the Internet of Things will ever take off. Maybe there will only be 500 million Internet of Things devices ever, this is not sure. However, IOTA has the biggest potential for me.
Let’s get to BNB. BNB has the same purpose as COSS. It is used on the Binance exchange to reduce your trading fees. That means, the value of BNB rises and falls with the success of Binance and Binance is now the second largest, most loved exchange. They currently process 10% of all crypto trades. Among the sea of scammy and unprofessional exchanges, Binance stands out as very professional, intelligent, fair, with excellent customer service. They will also soon release the first decentralized CryptoCurrency exchange in a month. I believe BNB will be among the top 10 cryptocurrencies within 1 year.
Let’s get to the final one Nano. It is my personal overall favourite. It is what Bitcoin always wanted to be, only a lot better. While Bitcoin is still struggling with high energy use, extremely low transaction volume and high fees upon increased usage, Nano has all that figured out already. Similar to IOTA, they are also a 3rd generation blockchain technology. They have zero fees, instant transactions and one millionth the energy usage of Bitcoin. Furthermore, they have been proven to work flawlessly while maintaining a 1000 tx/second volume. They are a payment processor.
Furthermore, it looks like Nano could replace BCH as a trading pair soon, since BCH trading pairs get little traffic, KuCoin has removed BCH trading pairs yesterday and there is already an exchange with that trades all of his currencies with Nano, called Nanex.
All in all, NANO and IOTA are on par for me while IOTA has more potential but also more risk, since it still has some security issues that haven’t been ironed out yet and they are somewhat reliant on the success of the Internet of Things. However, if the internet of things, really permeates our lives as described above, IOTA will replace Bitcoin and become the one most used cryptocurrency. Here is an excellent article about IOTA vs. Nano https://hackernoon.com/iota-vs-raiblocks-413679bb4c3e

Conclusion

Having said all this, if you believe that Bitcoin has now reached its full potential already and will never ever be worth more than now, don't invest in crypto anymore.
If you think that Bitcoin can potentially go to $20k again or to $40k or that cryptocurrencies will replace FIAT in 5 years, then you can look at 10x returns.
Many people fall victim to the cognitive bias of thinking Bitcoin is too risky, while the maximum risk is losing everything they invested, which can be $2,000. Sure, it is annoying to lose $2,000, but I put the possibility of Bitcoin never going to more than $7,500 at maybe 1%, while I put the likelhood of it going up to $20,000 or $30,000 at 60%. So, the odds are in your favor.
All in all, it's a large upside to a small downside. If you are very sceptical of Bitcoin, but you are looking to diversify your portfolio, $2,000 is a sane investment amount that yes, is annoying to lose, but won't change your life. If Bitcoin goes up again significantly, you will simply make a large amount of money. Small downside, large upside.
If you already have a significant amount of money in crypto, it's better to shift away from Bitcoin. Yes, you will probably make a 2x to 3x on Bitcoin as well, but you can make 50x from the best altcoins in the same time.
EDIT: I didn't include
There are several good coins in the top 100 still, Waves, Ziliqa, WTC, PIVX, Bat, REQ, ENG, SKY, LINK, though all of the high risk coins I mentioned do the same or have a bigger or equal potential as them 20x smaller market cap.
These top 100 coins aren't 20x better than the high risk coins, even if they were 5x times better, it would be better to invest in the high risk coins, because you would still make 4x more profit.
That's why the medium risk coins are only starting at number 133, 140 and 202. This makes them are undervalued for being the best utility coins currently.

My recent wire experience

Want to relay my recent experience to help other canucks entering the cryptocurrency scene. I wanted to invest 100K in both main coins and some alt coins. Depositing that amount can’t be done using ETF/bank-transfeetc. – the only reasonably quick way is to wire funds. For wires, most exchanges have a percentage based deposit fee – something that makes absolutely no sense to me. Whether you wire 1K or 1MM, the amount of work for the exchange is identical, so it should be a flat fee. Deciding on an exchange is more complicated than that though: each one has their own rules for minimums/maximums, trading fees, supported coins, holding periods, and withdrawal fees. They also can vary greatly on the amount of time verification takes. One thing to note is that pretty much all exchanges don’t charge a fee for inbound crypto transfers.
2 months ago I signed up for 10 exchanges (Coinbase/GDAX, Binance, Coinsquare, Kraken, ezBTC, QuadrigaCX, Bitfinex, Gemeni, Bittrex, Poloniex) and was verified on 7 of them (I’m still in queue for Gemeni, Bittrex, and Poloniex). Verification times gave me what I thought was a decent indicator of the level and quality of support I would receive.
Of these exchanges, some have what I believe to be relatively high trading fees (Gemeni .25%, Bittrex, .25%, ezBTC .30%, QuadrigaCX .50%) vs lower maketaker fees (GDAX 0/.3%, Binance .1/.1%, Gitfinex .1/.2%, Coinsquare .1/.2%, Kraken .16/.26%). Still others have high percentage based wire fees. And finally, there’s a big disparity between withdrawal fees: free on some exchanes, vs fixed rate based on the coin for others, vs Coinsquare’s insane fixed 0.0025 BTC regardless of what coin or the amount being withdrawn.
So here are some observations on the exchanges. Please note that the below is not a reflection on any of the people who work at the exchanges. I’m sure they are working as hard as they can and are doing their best. It’s just my experience. It’s also not financial advice. Also, I’m only human so feel free to offer corrections or better advice.
Coinsquare: amazingly fast verification time, and for very large deposits seems to likely be the best option as they will let you speak to a human being by phone and will waive the deposit fee (I didn’t know this until later though). I excluded them because of their high 0.5% percentage based deposit fee and their crazy high withdrawal fee. They also only have support for 6 coins.
QuadrigaCX: I had a terrible initial experience with QuadrigaCX’s support, so I immediately excluded them. They have high trading fees and there are many complaints of support tickets being ignored or having extremely lengthy wait times. They have a crazy high 1% percentage based CAD wire fee, but offer free USD wires. Note that they only support wires for large amounts.
GDAX/Coinbase: Loads of good reviews, but only has support for 4 coins. Seems like they also don’t have a fee for crypto withdrawals. You also can’t seem to wire CAD or USD funds directly to GDAX. I think you may have to wire USD funds to Coinbase and then transfer them over to GDAX (for free).
Kraken: I created an account but the verification page just appeared blank for me. After a few days, their support team got back to me telling me that they had a bug and that I needed to create a new account using a different email address and try again. That worked. I decided to use them as they seemed like the best all-around alternative. I was impressed with their support response (they gave me an answer that worked and responded in days as opposed to weeks), they offer a no-fee inbound CAD wire, support 16 coins, and have low (though not free) crypto withdrawal fees. They have also been around a while and have a good reputation (They were picked to handle MtGox claims). Wiring funds to them was a hair-raising experience though. You basically need to send your funds to an unknown bank in Tokyo, Japan. Kraken also has two slightly different sets of wire instructions: one that is on their website, and the other that their support folks send out. Only one of them mentions that you should tell your bank not to use an intermediary that will convert your currency. If you do things properly, and are lucky, you end up only paying ~$40 in fees. But chances are, you don’t, and end up paying 4%! (see https://www.reddit.com/BitcoinCA/comments/7rd6k8/fees_when_sending_to_krakencom/). You also have no idea how much the fees will be until the money finally shows up in your account. That’s tremendously unsettling. Luckily my bank branch manager was familiar with crypto currency wires and helped me do things properly. But, the wire took over 2 weeks to show up (Jan 18th), and Kraken support is so overloaded that they didn’t’ respond, despite me escalating my support ticket several times. I eventually had to resort to a reddit post to get a response to my support ticket. I gave support my wire receipt and answered lots of additional questions to help them try to “locate” it. Perhaps the worst part of my entire experience was that while my wire was being located, the entire crypto market tanked by 50%...and no one would respond to my support ticket…I felt helpless. A Kraken support rep a few days ago said that they are handing >50K new user registrations per day and have >20K new support tickets per day. I feel they should turn off new user registrations until they are capable of servicing existing customers. This is what their competitors have done. I found it disheartening to learn that the only way to get a response to my support ticket was to complain via social media --- many others have found the same. While I was waiting for my wire to appear Kraken had a >48h outage. Prior to the outage, the site was almost unusable as you’d receive constant 50x errors (I found this out prior to wiring my funds). After the outage, I find that their site is still barely usable. Pages take 10-15 seconds to load and when they do load many times they display errors so you have to continually retry until things work. At the end of the day though, they did come through for me: my wire arrived safely. So with my funds in Kraken, I tried to use them to purchase crypto. But no matter what I tried, none of the CAD dollar trading pairs would appear. I logged out and back in a few times and 15 minutes later, it suddenly started appearing. With the flakiness in Kraken’s platform, I had no choice but to transfer everything to a more stable and faster exchange:
Binance: These guys have their shit in order. Super simple site navigation once you get used to it, fast verification times, blazingly fast website and trading engine, more than 50 coins supported, etc. But, they don’t support fiat – you must use one of the other exchanges to buy crypto with fiat and then transfer in your crypto. Gotta say it again: everything is super fast. Not just the page loads, but also trading, email confirmations, and withdrawals. Trading takes a bit of getting used to as you aren’t really buying or selling crypto…you are instead “trading” one crypto coin for another. Depending on the coin you want to purchase, you might have to trade your coin for BNB (binance’s own coin) and then trade BNB for the coin you desire.
Be Your Own Bank: One final word of advice. Binance is awesome, but don’t trust anyone as despite everyone’s best intentions: no matter how secure a platform is, it can and will be hacked. As soon as you have done your shopping, transfer your coins off to your own wallet. This is why withdrawal fees are important.
You might be asking: in hindsight, if I had to do it all over again, what would I do differently? To wire CAD funds I would try to use Coinsquare if it’s a big amount (after re-reading other people’s recent reviews). For USD wires, I might try using Gemeni, but I still haven’t been verified by them and have been waiting for almost 2 months. Before using either I would re-test how long it takes for a support ticket to be responded to. If you do wire funds, don't wire an exact round amount like "10,000.00", instead I would wire "10,070.45" so that it's easier to locate if things go wrong. Once the account has been funded I wouldn’t hesitate to transfer everything to another exchange if I wasn’t happy with the platform, the number of coin offerings, or quality of service I was receiving: you can always come back when things improve.
Things change so quickly so not sure how helpful this will be…just wished I had known some of the above before starting.

Blockchain Wallets

Hello! My name is Inna Halahuz, I am a sales manager at Platinum, the largest listing service provider for the STO and ICO projects. We know all about the best and most useful STO and ICO marketing services.
By the way, we developed the best blockchain platform:
[Platinum.fund] (https://platinum.fund/sto/)
We also created the UBAI, the unique educational project with the best and most useful online courses. We not only share our knowledge but also help the best graduates to find a job! After finishing our courses you will know all about crypto securities, ICO and STO advertizing and best blockchain platforms.
What a Blockchain Wallet is? What is its purpose?
Find the answer after reading this article.
Public/Private Key
The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver.
Accessing wallets
Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals.
Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets.
Types of Wallets & Storage Methods
The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners.
Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens.
Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples.
Hardware wallets — LedgeTrezoAlternatives
Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers.
Paper Wallets
Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper!
Real World Historical Examples of Different Wallet Types
Web Wallet: Blockchain.info Brief mechanism & Security Blockchain.info is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by blockchain.info has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops.
Neon Wallet
The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as https://bitcoinpaperwallet.com/ and https://walletgenerator.net/. They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible.
Real World Example — Poor Practices
MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets.
In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes.
Case Study: Good Practice Binance, the Attempted Hack
During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “binance.com”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt.
Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations
As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange.
Hardware Wallets Advantages and Limitations
We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations.
Paper Wallets Advantages and Limitations
Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever.
Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security
Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose.
You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait.
How to Monitor Funds
There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. Blockchain.info is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including nanoexplorer.io for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor.
That’s not all! You can learn how to transfer and monitor the funds in and out of your wallet by clicking on the link.
