Note: I was intending to finish and publish this article about 10 months ago which was the red hot timing (the 1st half of 2018) for the Cryptocurrency. It went from $3,000 USD to $22,000 USD in less than an year. Yet I didn't get it done until now. And after almost another year passed, it looks more like a fad than a future (my opinion on most of the cryptocurrencies not on blockchain technology)...
First of all, I would like to clarify my role here on this writing. I am not an expert on crypto or blockchain. I am not trying to be an expert here or to speak out for some reasons. I am writing this because I would like to know more and learn more on this terrain. I want to dig a little bit deeper and know a little bit better on this hot selling cake since, really, it's still a big foggy area for the mainstream.
What is a “Cryptocurrency”?
“A cryptocurrency is a digital or virtual currency that uses cryptography for security.”
“A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets.”
It is not possible not to mention Bitcoin when the topic is on the cryptocurrency. You might think that those two (“Cryptocurrency” and “Bitcoin”) are the same thing; however, “Cryptocurrency” concept was already invented way before its hot red time with published paper, “b-money” by Wei Dai (戴维), and a mechanism which was designed but never implemented – “Bit gold” by Nick Szabo in 1988. Many people, even the information you get from Wikipedia credited Satoshi Nakamoto, the creator of Bitcoin, on inventing Blockchain technology; however, it’s already being structured and put on paper in 1998 through “b-money” paper and “Bit gold” design. Let’s take a look at the “bit gold” structure excerpted from Wikipedia as follows,
“In Szabo’s bit gold structure, a participant would dedicate computer power to solving cryptographic puzzles. In a bit gold network, solved puzzles would be sent to the Byzantine fault-tolerant public registry and assigned to the public key of the solver. Each solution would become part of the next challenge, creating a growing chain of new property. This aspect of the system provided a way for the network to verify and time-stamp new coins, because unless a majority of the parties agreed to accept new solutions, they couldn’t start on the next puzzle”
This (above) is literally the explanation of the blockchain technology applied to the core of the Bitcoin invention in 2009 (the genesis block was created on 03/Jan/2009 by Satoshi Nakamoto). We will have a designated section for Bitcoin later in this writing; hence we will hold on other things we would like to know and learn more in that section.
So, what’s the cryptocurrency? After you go over the above writings, you might be still not clear about what that is? or how does that work? In order to make it simple, I will use the very principle, banking system, cryptocurrency against the most to explain how it works.
Central banking system control and verify all the records of the transactions
In banking system which is also called centralized money system, we put our money in the bank. Whenever we want to use our money, we go through (in person, via ATM, or online … etc) the bank, withdraw money, and make purchases. Central banking system control and verify all the records of the transactions. It’s how the banking system works.
no central controlling organization; No regulations and it is anonymous.
It’s close to impossible to alter the transaction once it’s completed.
For cryptocurrencies, they are still money but just in a different form (digital format. you can compare it as using credit cards since you don’t hold physical bills to buy and sell). The major difference here is that there is no central controlling organization in place to record any transactions of yours. In fact, there is no authority can do that at all. No regulations and it is anonymous. Meaning that you can buy and sell anonymously. So, your next question should be that how are transactions being verified? Where do you store your money? How are you going to withdraw money? If there is no authority handling all these activities, how can you safely and securely use cryptocurrencies?
In cryptocurrency world, you have your own wallet storing all your cryptocurrencies. Only you know your own wallet either locally existing in your computer (or USB drives or even on a piece of paper) or you can choose one of many cloud wallets to handle this job. Once you want to purchase something (or sell some stuff), you do it (money transfer) through your wallet and the transaction will be verified by that specific cryptocurrency network (e.g., Bitcoin network or Ethereum network … etc). Since it’s a peer-to-peer network, there is no central point to control the record but dispatching to many end points. Meaning that the record of transactions is owned by many end points (they are called miners who set up computers and registered to a cryptocurrency network of their choice and verifying transactions through solving problems given by the cryptocurrency network. That specific cryptocurrency network miners who you can see them as equivalent of bank clerks helping you to complete your transactions). Hence, it’s close to impossible to alter the transaction once it’s completed. Why? Since one record is stored on so many different end points, you have to hack into all those end points and alter that record on all those computers. It’s impossible to get it done since you also need to know how many end points having that record too and also locate those computers which is an unachievable mission. That’s one (security & integrity) of the reasons that why people are exciting about and embracing cryptocurrencies.
Security – secured by military grade cryptography. Nobody can charge you money or make a payment on your behalf.
Note: For how the crypto-wallet works and how end points (computers/machines owned and operated by people registered with cryptocurrency networks) verify transactions, you can read those on the Bitcoin section following later.
By the way, if you lose your access to your wallet, you lose all your money storing in it since there is no (central) authority having any records of your money/transactions. You money will not be your money anymore. So, will those money be owned by others? Well… nope… since no one owns that wallet so no one owns those cryptocurrencies unless (or until) someone hacks into it. The hacking and stealing has become the biggest problem/fear in the cryptocurrency industry along with ICO frauds. I will also talk about them later in this writing.
The biggest problem/fear in Cryptocurrency – hacking/stealing & ICO frauds
Debate of the Decade – Cryptocurrency is NOT a Currency
There are lots of negative opinions about crypto (from now on, I am going to just use “crypto” to refer to cryptocurrency in this writing). Some go even further referring that “crypto is the biggest scam in the human history”. There are some truth behind this since, really, if you dissect the value of the currency (we are talking about definition here) traditionally, crypto is definitely a scam and all the services relating to it are more like frauds than legit businesses.
Let’s take a look at the definition of “Money/Currency”:
1) A storehouse of value.
2) A unit of account.
3) A medium of exchange.
When you dive into fitting crypto with the definition of currency, you will find out that it’s difficult to put crypto into the money/currency territory.
a storehouse of value
For “a storehouse of value”, the volatility alone kills this definition already. How can anyone uses an asset fluctuates for hundreds or even thousands of dollars a day (or hours) to store value?
A store of value is the function of an asset that can be saved, retrieved and exchanged at a later time, and be predictably useful when retrieved. More generally, a store of value is anything that retains purchasing power into the future.
It says that “a store of value is anything that retains purchasing power into the future”. Is crypto going to be able to retain any purchasing power into the future? What if you buy at $6K (a coin) and later that month when you want to use that coin you purchased and found out that the value of that coin is only a mere $100 USD? Yes, you can still buy something but talking about retaining the purchasing power? It really tumbles on this clarification when it fluctuates like riding a rollercoaster.
A unit of account
“A unit of account”, the core purpose of the crypto fails on this. The account for whom when it’s anonymous?
A medium of exchange
“A medium of exchange”, it’s getting widened but compared with traditional currencies, it’s really not that much to say to support this point. Also, it’s only bitcoin (maybe Ethereum can be included in this pond) as a crypto(-currency) that is widely being recognized by the public. Therefore, crypto barely meets this criterion.
Note: Bitcoin really has come a long way. I went to a food court nearby yesterday (again, about 10 months ago since I just picked up this writing after 10 months when it was first drafted... however, the situation on this criterion hasn't changed much though) and I saw a burger stand put a huge digital display showing that they now "accept bitcoin payment".
Based on those 3 criteria of the definition for currency alone, crypto really cannot be define as currencies. The best it can go in this category is the “high risk and high reward investment”. It’s really not a currency if you stand by the arguments above.
Crypto dose NOT fit into currency category.
Crypto – high risk and high reward investment
Crypto(-currency) & Blockchain Technology
Just like many of you that I got confused when I first heard so many news talking about it. It’s the stupid side-effect in technology that there are so many terms, so many definitions (of so many simple things), and so many acronyms (to describe easily understandable terms) to mess up our brains. Just take acronyms as an example that it really does not help that much when a content wants to get its target audiences into understanding specific topics. What does “SaaS” mean to you? If you aren’t seeing it before, a couple of question marks would likely emerge in your head and it really means nothing to you at all. That’s right, most of the contents will later (if at all) show you the full term of the acronyms they just mentioned. So … “SaaS” is “Software as a Service”. Really … It is easier, simpler, and clearer just put the full text in the content in stead of the acronym. The acronyms might be a norm in a specific industry but, in terms of getting your target audiences hooked, it really doesn’t help.
Blockchain” is a technique to construct Crypto(-currency)
For crypto and blockchain technology, those two are totally different things. “Blockchain” is a technique to construct Crypto(-currency)”. One of the basic principles in making crypto a crypto is that it is secure which means it’s impossible to be altered (referring to transactions/records here). All the records/transactions are stored in so many different places (end points). How does crypto do that? One of the many implementations in it is via a technique and it’s called “blockchain”.
I will grab a paragraph from our site – “techinwire.com” – further explaining “blockchain” technology a bit as follows,
“Just think of a group of 10 people who all have a piece of paper having a shopping list items on those pieces of paper (let’s call those pieces of paper “shopping sheets”). Whenever one of these 10 people buys an item, that item (as well as how much of the item, which person purchased that item, and the time of the purchase … etc.) will be written onto all of those shopping sheets owned by those 10 people on exactly same space on the sheet (those sheets are identical by the way). Therefore, no matter how many items are being bought by which person, the records of those purchases will appear on every single one of those 10 sheets on exact same space of the sheet once those purchases are being made.”
You can think that every single of your transactions is being stored in a (data) block (every transaction forms a different block) and being distributed to many different end points (computers owned by different people). Whenever a transaction is made, a block will be formed and dispatched to end points to be attached to a chain of blocks relating to that account (anonymous of course). Therefore, there are many (exactly same) records on those transactions existing in the Internet-universe. It’s impossible to alter since you will need to remake all those records on all the end points in order to crack/hack it successfully. Those records on those end points are the same as traditional bank ledgers and they are called “cryptocurrency ledgers”.
Blockchain – A chain of blocks maintain a cryptocurrency ledger for transactions on specific account to ensure secure transactions/records anonymously and maintain the integrity of the transactions
Crypto(-currency) – a digital asset that is created by using blockchain technology and aiming to use as a unit of exchange (payment) in the market
Note: For many people, crypto has already become a mean of payment; however, for others, it's still something they don't quite buy in yet (or never). Hence, I put my definition of crypto(-currency) as a digital asset aiming to be a unit of exchange above. Really, it seems that it will based on the momentum of the bitcoin current has; however, there are still a lot of things need to be figured out before the path is clear. So, I will stick with what I feel as of now.
How the Cryptocurrency Work?
Even though I mentioned that, to me, crypto is an asset aiming to be a payment unit, it has already become a payment alternative to a lot of people (remember that I mentioned that local burger food stand already accepting bitcoin as a mean of payment?). Therefore, I would like to dive in to explain how the crypto works.
Remember what we have on the traditional banking example that bank clerks help us complete transactions and the banks act as the central authorities verifying (transactions/records) and storing money for us? The crypto acts the same way as well (through different terms and approaches).
Before I give some examples, I want to mention three phrases from crypto market/industry/field here. Those phrases are “crypto mining” which leads to “crypto miners”, and also “proof of work”.
It’s really confusing to use mining to describe how crypto works. To me, just using “verifying” is way more clear on this turf though (or even “problem solving” should be more appropriate. But, as we all know, fancy names matter in business, isn’t it?).
Anyway, the “crypto mining” is a way that end points (computers) verify our crypto transactions and put verified transactions into a data block and add that data block onto the chain of block (blockchain) of our account.
It’s a program designed to solve difficult problems through algorithms to verify crypto transactions. It is specific to each different crypto (e.g., Bitcoin network having its Bitcoin miners. Ethereum has its Etherum miners… etc).
When a transaction happens, a problem (or a puzzle) will be created for that specific transaction. Ensuing that there are lots of miners (different end points) go on to run through all the possible solutions to find the right answer to solve that specific problem/puzzle. Which miner finds the right solution first, that miner verifies that transaction, and that miner gets rewarded by receiving crypto(-currencies) as a reward in return. This is how the crypto transactions being verified and, also, how the crypto being generated (if you ever wonder how the cryptocurrencies being generated when there is no central bank controlling it).
Proof of Work
Problems need to be hard to solve – taking a lot of computing power
Answers must be easily to check
As I have been trying to get everyone (and myself too) who might happen to read this writing into an easy route of understanding how the Crypto works, I found out that there might actually have no easy way to do so unless we really have the basic understanding of how the whole verifying process works including the concept of “Proof of Work” which is the factor powered the integrity of the crypto network.
I will start giving a simplest explanation of the “Proof of Work” and then walking you through examples and demonstrations from credible sources. Hopefully, we all can be clear on this “PoW” concept at the end of this section.
Two Facts that "Proof of Work" Follows: 1) Problems need to be hard to solve - taking a lot of computing power 2) Answer must be easily to be checked and be confirmed
Let’s use Bitcoin as an example which use SHA-256 Hash function to check if a problem is solved. As we mentioned that there a problem will be given when transactions happen. Miners will receive that problem and race to find the right answer. The “SHA-256 Hash function” is the magical box used to verify if the given answer is correct. Put the problem and the given answer into the “SHA-256 Hash function” magical box and it will confirm whether the correct answer is given. Let’s watch a video published by Khan Academy explaining “Proof of Work Protocol” below,
It sounds abstract at this point, doesn’t it? In fact, without any demonstration, it’s really hard to formalize any useful knowledge in our heads. For instance, who gives the problem to solve? Who is solving the problem? and also that how to check and confirm if the given answer is correct?
Let’s go through the following video and I will give answers to questions listed above.
Now you should have a basic understanding of how crypto works. So, how about the questions we have above? Let’s dive into them right away.
Who Gives Problems to Solve?
When a transaction happens (meaning that you use any of the bitcoin wallets to initiate a transaction), the problem is broadcasted to the bitcoin network (the crypto network of your choice… e.g., Bitcoin network, Ethereum network … etc) all around the world (over the Internet of course).
Who is Solving the Given Problems?
The bitcoin miners on bitcoin network. All the miners on the bitcoin network can receive the problems and race to solve the problems.
How to Check and Confirm if the Given Answer is Correct?
As you can see from the video above, when the problem is being solved a new block will be created. Since it’s a peer to peer network and everyone can join the network, each node will receive the newly created block and can check the validity of the block. Once it’s checked out, the new block will be attached to the chain on each node around the globe (everyone is allowed to join the network and when he/she joins the network, he/she gets the full copy of the blockchain).
Now we have gone through the PoW protocol and how blockchain works, I think that it’s time to explain the crypto-wallet. I know that it feels I am walking backward on this writing; however, I am just letting things unfold by themselves. So, without further ado, let’s get into the cryptocurrency wallet.
What is Cryptocurrency Wallet?
I will start with the explanation from Wikipedia since it’s the goto place when we want to find some quick definitions of something we are curious about.
“A cryptocurrency wallet stores the public and private keys which can be used to receive or spend the cryptocurrency.”
Terse enough, isn’t it? However, it does not say much about how it really works though. Also, where can you get those cryptocurrency wallet?
“Cryptocurrency wallet” – a program that can secure, verify, and track the transactions of crypto of yours on the decentralized network.
In fact, a “cryptocurrency wallet” isn’t a wallet. It’s just a metaphor of a program that can secure, verify, and track the transactions of crypto of yours on the decentralized network. Put it this way that a “cryptocurrency wallet” is a program which is able to initiate transactions by using the private key and public key assigned to the program (wallet) to verify the ownership of the specific account, complete, and track those transactions as well as the account balance. A “cryptocurrency wallet” does not actually store any crypto(s) or transactions, instead, it’s a key to get all those informations from public ledgers (nodes) all over the world. Transactions/records are stored in the public ledgers which are minders’ locations (e.g., mining programs).
A “cryptocurrency wallet” does not actually store any crypto(s) or transactions, instead, it’s a key to get all those informations from public ledgers (nodes) all over the world
It leads to a huge issue which all cryptos have. It’s not the volatility that everyone thinks but it’s the vulnerability caused by the underlying value of cryptos, “anonymous”. Because it’s anonymous and the only validation of the ownership is the access to your cryptocurrency wallet, you will lose every single crypto you’ve ever own if your wallet is hacked or simply that you just forgot your password.
How Does the Cryptocurrency Wallet Work?
Since a cryptocurrency wallet is a program store your public and private key with crypto protocols (depending on which crypto you choose to store. For instance, bitcoin has it’s own algorithms and ethereum has a different one to form blockchains which are stored in the public ledgers/nodes), you will be able to monitor your balance, send and receive cryptos, and conduct other operations.
A bitcoin wallet address is a hashed version of your public key. Every public key is 256 bits long and the final hash (your wallet address) is 160 bits long. The public key is used to ensure you are the owner of an address that can receive funds.
A Bitcoin address is a 160-bit hash of the public portion of a public/private ECDSA keypair. Using public-key cryptography, you can “sign” data with your private key and anyone who knows your public key can verify that the signature is valid.
A new keypair is generated for each receiving address. The public key and their associated private keys (or the seed needed to generate them) are stored in the wallet data file.
Bitcoin allows you to create as many addresses as you want, and use a new one for every transaction. There is no "master address": the "Your Bitcoin address" area in some wallet UIs has no special importance. It's only there for your convenience, and it should change automatically when used.
When you send cryptos to someone, you are signing off your ownership of the coins to that person’s wallet (wallet address). To receive and unlock the fund you sent, (easy to imagine answer here) the coin receiver’s wallet address must match the public/private keypair hashed by using public-key cryptography stored in the wallet. Basically, the wallet’s private key and public key generated the wallet’s address and when a fund sent to an address, it must be verified to see if that fund is meant to be sent to that wallet. If the fund is verified, the balance in your crypto wallet will decrease (again, the record is stored in the public ledger not in the wallet itself); and the balance in the coin receiver’s wallet will increase accordingly. All those transaction information are put in a data block, dispatched, and attached to blockchains which are stored in all nodes in the crypto network (e.g., if you sent bitcoins, it’s in bitcoin network… etc).
Types of Cryptocurrency Wallets
There are several different types of crypto wallets on the market and each type has its own purpose in terms of accessibility and security.
1) Desktop Wallet
Wallet software are downloaded and installed on your computer. You can only access your wallet on that single computer you install your wallet on. Desktop wallet offers one of the highest security protection on the crypto wallet turf. Most people who use the Desktop wallet use it offline exclusively since once it’s online, it opens up a door for hackers to attack. Also, if your computer died and you didn’t backup your wallet, your entire coins collections will be lost.
2) Hardware Wallet
This is the 2nd most secure way of storing your cryptocurrencies (BTW, the Desktop wallet isn’t the most secure one. We will talk about the most secure type of wallet on the very last of this section).
Basically, it’s a Desktop wallet program being parted and put into two different containers. One is …well… still a desktop which is a computer in general, and the other is a hardware device such as USB storage hardware. Why is that? Because it will increase the security level by preventing the wallet that you store your private key from being accessed on the Internet. The hardware wallet which is the USB storage liked device is the wallet that you connect to your computer whenever you would like to initiate a transaction or check on your balance. The other part of the program located on the computer will be responsible of accessing the Internet once your ownership of that specific wallet being authenticated. After then, you will be able to perform operations through the software on the computer.
3) Mobile Wallet
You should be able to guess what that is already, right? It’s a mobile program storing your wallet private key and also capable of performing other crypto operations such as initiate transactions, receiving transactions, and checking balance… etc. Although this is very convenient and useful (since it can be easily used even on retail stores if they accept crypto as payments), it’s also more risky of having the mobile crypto wallet. First, your phone is online all the time so it’s prone to be exposed to malicious viruses and hackers. Second, if you lose your phone and you didn’t backup your wallet (please, not on your phone since … the scenario is that … you lose your phone), you are screwed. You will lose all the coins associated with that wallet (remember that crypto wallet isn’t really the place that your coins are being stored rather a key to access your coins vault).
crypto wallet isn’t really the place that your coins are being stored rather a key to access your coins vault
4) Web Wallet
Also called “Online Wallet” which is a website offers a service allowing you to store your cryptocurrencies securely. Basically, just think that it’s a bank that you need to register to create an account (in this case, it’s your crypto wallet). After you successfully created your account, you will be able to access your web wallet on that web wallet service provider’s platform. Again, you are the only one who has the access to your wallet since you are the only one who holds the private key of your wallet. If you forgot to back that up, you will lose the access to your web wallet too (meaning that you will lose all your coins associated with that web wallet).
Web wallet is the most insecure way of managing/operating cryptocurrencies since it’s exposed to the hackers and malicious programs ALL THE TIME. If you decide to go for this route, you should look for a multi-signature web wallet. A multi-signature web wallet required multiple parities to sign private keys (just think that it needs to have multiple keys to unlock an account) in order to initialize a transaction.
Web wallet is the most insecure way of managing/operating cryptocurrencies
5) Paper Wallet
the most secure crypto wallet
Just like the mobile wallet, you must have an idea what the “paper wallet” is. But, how does it work?
Note: Hot Wallet (or Hot Storage) & Cold Wallet (or Cold Storage) They simply refer to whether or not they are connecting to the Internet. For instance, a hardware wallet is a cold wallet/storage; however, a web wallet is a hot wallet/storage.
A paper wallet is an offline cold storage method of saving cryptocurrencies. It can be a piece of paper having your wallet’s public key and private key information. Or it can be a QR code including your wallet (keys) information.
Paper Wallet generating sites –
A paper wallet is extremely secure but extremely prone to get lost. Why? Well… it’s a piece of paper and it’s just like all the valuable materials you own that you need to protect them 24/7. You should put it in a secure place but also you need to back that up as well. If you lose that piece of paper, you lose all of your coins securely associated with that wallet forever.
Where Can You (and How to) Get A Cryptocurrency Wallet?
Crypto has been on the spotlight for a while. Not only has it been rising since its inception, but also has it been getting into high stake investment games (e.g., people are really betting their livelihood on cryptos). Just like everything else, whenever there is a demand, there will be abundant supplies sprouting all over. Hence, we are going to just talk about Bitcoin wallets here because of three reasons. First, there are too many cryptocurrencies out there as of today. It’s like before the stock market reaches the climax and then tumbling down that new stocks (now are new cryptos) announced and appeared in a record speed (As of September 2017, over a thousand cryptocurrency specifications existed – https://en.wikipedia.org/wiki/Cryptocurrency). Second, you really can use your bitcoin investment as a payment method on your daily purchases. More and more retails start accepting bitcoin payments. Ergo, you should get a mobile wallet (small amount bitcoins associated with it) for your daily purchase purpose and a cold wallet for your mass investment. Third, whenever your hard earned money is involved, we should play extra safe when we give suggestions.
get a mobile wallet (small amount bitcoins associated with it) for your daily purchase purpose and a cold wallet for your mass investment
For the above reasons, we decided to just refer to the wallets that Bitcoin.org listed on its site. Those wallets (you can find 4 types of wallets there except the paper wallet type) are officially endorsed by the Bitcoin.org so the chance of being screwed is relatively low compared with other offerings (we are talking about not only the legitimacy of the wallet here but also the how secure those wallets are). So, just heading to Bitcoin.org (https://bitcoin.org/en/choose-your-wallet) and start picking a wallet (or couple of wallets) of your choice if you seem like to do so.
For the paper wallet, you can go to the following two sites to generate your paper wallet. Paper Wallet generating sites - Bitaddress.org (https://www.bitaddress.org/) or Walletgenerator.net (https://walletgenerator.net/).
In addition, you should not hold all of your coin investments in ONE WALLET ONLY especially if that wallet is an hot wallet. You are risking to lose all your crypto investments if you do so. No matter how secure the platform behind it, hot wallets are prone to be hacked. It’s a common sense that when the stake is high, we can be sure that people are working on getting into it. We don’t need to dig into too far away for cautionary tale incidents (yes, hackers have been robbing those hot wallet platforms for years. Although the cryptocurrency is still in it’s infancy, the amount of stolen cryptos has reached $1.2 billions USD. That’s right. It’s a letter “B”. $1.2 Billion worth of cryptocurrencies have been stolen by hackers), just the recent news alone will shock you (again, this writing was drafted about 10 months ago).
$530 million cryptocurrency heist may be biggest ever Hackers Stole $50 Million in Cryptocurrency Using 'Poison' Google Ads
The best practice is to have, at least, two different types of wallets. One is for the daily use and can access to the Internet easily. This hot wallet should only hold small amount of your coins just in case some bad things happen to the service behind that wallet.
The other wallet you should have is a cold wallet. You should hold majority of your coin investments in it. Since it’s a cold wallet, the risk of being hacked is close to zero. However, you should backup your wallet in case you lose it especially if you use a paper wallet.
Although we still have something (in fact, still quite a few) want to figure out ourselves (also provide information to you), we will stop right here since it’s already a pretty long writing AND it sort of walks through the major steps of acquiring the basic knowledge to help the mainstream get into the crypto game arena. There will be a part 2 relating to crypto and the whole Bitcoin history along with what kind of problems it is aiming to solve later on. The takeaway here is that everyone living in the Internet age should have an easier way to get acquainted with the new finance cool kid in town – “Cryptocurrency”. We hope that we provided a way here. As always, we welcome suggestions anytime.
Happy investing ~~~!
