Cryptocurrencies are digital tokens. They are a type of digital currency that allows people to make payments directly to each other through an online system. Cryptocurrencies have no legislated or intrinsic value; they are simply worth what people are willing to pay for them in the market. This is in contrast to national currencies, which get part of their value from being legislated as legal tender. There are a number of cryptocurrencies - the most well-known of these is Bitcoin. Today cryptocurrencies have become a global phenomenon known to most people.
A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on blockchain technology, a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation:
• Cryptocurrency is an internet-based medium of exchange which uses cryptographical functions to conduct financial transactions. Cryptocurrencies leverage blockchain technology to gain decentralization, transparency, and immutability.
• The most important feature of a cryptocurrency is that it is not controlled by any central authority: the decentralized nature of the blockchain makes cryptocurrencies theoretically immune to the old ways of government control and interference.
• Cryptocurrencies can be sent directly between two parties via the use of private and public keys. These transfers can be done with minimal processing fees, allowing users to avoid the steep fees charged by traditional financial institutions.
Nowadays, you'll have a hard time finding a major bank, a big accounting firm, a prominent software company or a government that did not research cryptocurrencies, publish a paper about it or start a so called blockchain project.
Cryptocurrency is a digital money, created from code.
Free of all governmental oversight, The cryptocurrency economy is monitored by a peer-to-peer Internet protocol.
Cryptocurrency is an encrypted string of data or a hash, encoded to signify one unit of currency.
What Is Cryprocurrency.
Origin Of Cryptocurrency
Few people know, but cryptocurrencies emerged as a side product of another invention. Satoshi Nakamoto, the unknown inventor of Bitcoin, the first and still most important cryptocurrency, never intended to invent a currency.
In his announcement of Bitcoin in late 2008, Satoshi said he developed "A Peer-to-Peer Electronic Cash System." His goal was to invent something; many people failed to create before digital cash.
The single most important part of Satoshi's invention was that he found a way to build a decentralized digital cash system. In the nineties, there have been many attempts to create digital money, but they all failed.
After seeing all the centralized attempts fail, Satoshi tried to build a digital cash system without a central entity. Like a Peer-to-Peer network for file sharing.
This decision became the birth of cryptocurrency. They are the missing piece Satoshi found to realize digital cash. The reason why is a bit technical and complex, but if you get it, you'll know more about cryptocurrencies than most people do.
To realize digital cash you need a payment network with accounts, balances, and transaction. That's easy to understand. One major problem every payment network has to solve is to prevent the so-called double spending: to prevent that one entity spends the same amount twice. Usually, this is done by a central server who keeps record about the balances.
In a decentralized network , you don't have this server. So you need every single entity of the network to do this job. Every peer in the network needs to have a list with all transactions to check if future transactions are valid or an attempt to double spend. But how can these entities keep a consensus about these records?
If the peers of the network disagree about only one single, minor balance, everything is broken. They need an absolute consensus. Usually, you take, again, a central authority to declare the correct state of balances. But how can you achieve consensus without a central authority? Nobody did know until Satoshi emerged out of nowhere. In fact, nobody believed it was even possible.
Satoshi proved it was. His major innovation was to achieve consensus without a central authority. Cryptocurrencies are a part of this solution - the part that made the solution thrilling, fascinating and helped it to roll over the world.
Features Of The Bitcoin System
Bitcoin was launched in 2009, a year after a report that described the Bitcoin system was released under the name Satoshi Nakamoto. The system was designed to electronically mimic features of a cash transaction. It was designed to allow peer-to-peer (or person-to-person) transactions, without the need to know or trust the other person in the transaction, and to occur without the need for a central party (such as a bank). Unlike conventional national currencies such as U.S. dollars, which get part of their value from being legislated as legal tender (the law says it must be accepted as a payment), Bitcoin and other cryptocurrencies do not have any legislated or intrinsic value. Instead, the value of Bitcoin is determined by what people are willing to pay for it in the market.
One feature of the Bitcoin system is that the supply of bitcoins increases at a pre-determined rate and is capped at around 21 million (with each bitcoin able to be subdivided into 100 million satoshis or 0.00000001 bitcoins). Because of this the supply of bitcoins has been commonly compared to the supply of a scarce commodity, such as gold.
The Bitcoin system allows transactions to occur directly from person to person without requiring a central party (such as a bank) to verify or record the transactions. This is unlike most conventional payment methods, such as electronic bank transfers, which rely on a central party to keep and update records of transactions. For example, commercial banks maintain a record of their customers' account balances, deposits and withdrawals.
Instead, the Bitcoin system uses "blockchain" technology to record transactions and the ownership of bitcoins. This is essentially technology that connects groups of transactions ('blocks') together over time (in a 'chain'). Each time a transaction occurs, it forms part of a new block that is added to the chain. As a result, the blockchain provides a record (or database) of every bitcoin transaction that has ever occurred, and it is available for anyone to access and update on a public network (this is often referred to as a 'distributed ledger'). The integrity of the Bitcoin system is protected by 'cryptography', which is a method of verifying and securing data using complex mathematical algorithms (or codes). This makes the system very difficult to corrupt.
Bitcoin transactions are verified by other users of the network, and the process of compiling, verifying and confirming transactions is often referred to as 'mining'. In particular, complex codes need to be solved to confirm transactions and make sure the system is not corrupted. The Bitcoin system increases the complexity of these codes as more computing power is used to solve them. A new block of transactions is compiled approximately every ten minutes. 'Miners' want to solve the codes and process transactions because they are rewarded with new bitcoins (currently 12.5 new bitcoins per block).
The increase in competition between miners for new bitcoins has seen large increases in the amount of computing power and electricity required (which is often used for air conditioning to cool computer systems). While it is difficult to calculate with precision, some estimates suggest that the annual energy consumption of the Bitcoin system is similar to that of countries like Greece, Colombia or Switzerland.
How Miners Create Coins And Confirm Transactions
Let's have a look at the mechanism ruling the databases of cryptocurrencies. A cryptocurrency like Bitcoin consists of a network of peers. Every peer has a record of the complete history of all transactions and thus of the balance of every account.
A transaction is a file that says, "Bob gives X Bitcoin to Alice" and is signed by Bob's private key. It's basic public key cryptography, nothing special at all. After signed, a transaction is broadcasted in the network, sent from one peer to every other peer. This is basic p2p-technology.
Cryptocurrency Transaction Steps Details:
1. Someone requests a transaction.
2. The requested transaction is broadcast to a P2P network consisting of computers known as nodes.
3. The P2P network of nodes validates the transaction and the user's status using known algorithms.
4. Once verified, the transaction is combined with other transactions to create a new block of data for the ledger.
5. The new block is then added to the existing blockchain in a way that is permanent and unalterable.
6. The transaction is complete!
7. A verified transaction can involve cryptocurrency, contracts, records, or other information.
8. Cryptocurrency is a medium of exchange, created and stored electronically in the blockchain, using encryption techniques to control the creation of monetary units and to verify the transfer of funds. Bitcoin is the best known example.
9. Has no intrinsic value in that it is not redeemable for another commodity.
10. Has no physical form and exists only in the network.
11. Its supply is not determined by a central bank, and the network is completely decentralized.
Cryptocurrency Transaction Steps Details.
The transaction is known almost immediately by the whole network. But only after a specific amount of time it gets confirmed. Confirmation is a critical concept in cryptocurrencies. You could say that cryptocurrencies are all about confirmation.
As long as a transaction is unconfirmed, it is pending and can be forged. When a transaction is confirmed, it is set in stone. It is no longer forgeable, it can't be reversed, it is part of an immutable record of historical transactions: of the so called blockchain.
Central to the appeal and functionality of Bitcoin and other cryptocurrencies is blockchain technology, which is used to keep an online ledger of all the transactions that have ever been conducted, thus providing a data structure for this ledger that is quite secure and is shared and agreed upon by the entire network of individual node, or computer maintaining a copy of the ledger. Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories.
Many experts see blockchain technology as having serious potential for uses like online voting and crowdfunding, and major financial institutions such as JPMorgan Chase (JPM) see the potential to lower transaction costs by streamlining payment processing. However, because cryptocurrencies are virtual and are not stored on a central database, a digital cryptocurrency balance can be wiped out by the loss or destruction of a hard drive if a backup copy of the private key does not exist. At the same time, there is no central authority, government, or corporation that has access to your funds or your personal information.
Only miners can confirm transactions. This is their job in a cryptocurrency-network. They take transactions, stamp them as legit and spread them in the network. After a transaction is confirmed by a miner, every node has to add it to its database. It has become part of the blockchain.
For this job, the miners get rewarded with a token of the cryptocurrency, for example with Bitcoins. Since the miner's activity is the single most important part of the cryptocurrency-system we should stay for a moment and take a deeper look at it.
Principally everybody can be a miner. Since a decentralized network has no authority to delegate this task, a cryptocurrency needs some kind of mechanism to prevent one ruling party from abusing it. Imagine someone creates thousands of peers and spreads forged transactions. The system would break immediately.
So, Satoshi set the rule that the miners need to invest some work of their computers to qualify for this task. In fact, they have to find a hash - a product of a cryptographic function - that connects the new block with its predecessor. This is called the Proof-of-Work. In Bitcoin, it is based on the SHA 256 Hash algorithm.
You don't need to understand the details about SHA 256. It's only important you know that it can be the basis of a cryptologic puzzle the miners compete to solve. After finding a solution, a miner can build a block and add it to the blockchain. As an incentive, he has the right to add a so-called coinbase transaction that gives him a specific number of Bitcoins. This is the only way to create valid Bitcoins.
Bitcoins can only be created if miners solve a cryptographic puzzle. Since the difficulty of this puzzle increases the amount of computer power the whole miner's invest, there is only a specific amount of cryptocurrency token that can be created in a given amount of time. This is part of the consensus no peer in the network can break.
Importance Of Mining
Miners are the single most important part of any cryptocurrency network, and much like trading, mining is an investment. Essentially, miners are providing a bookkeeping service for their respective communities. They contribute their computing power to solving complicated cryptographic puzzles, which is necessary to confirm a transaction and record it in a distributed public ledger called the Blockchain.
One of the interesting things about mining is that the difficulty of the puzzles is constantly increasing, correlating with the number of people trying to solve it. So, the more popular a certain cryptocurrency becomes, the more people try to mine it, the more difficult the process becomes.
A lot of people have made fortunes by mining Bitcoins. Back in the days, you could make substantial profits from mining using just your computer, or even a powerful enough laptop. These days, Bitcoin mining can only become profitable if you're willing to invest in an industrial-grade mining hardware. This, of course, incurs huge electricity bills on top of the price of all the necessary equipment.
Currently, Litecoins, Dogecoins and Feathercoins are said to be the best cryptocurrencies in terms of being cost-effective for beginners. For instance, at the current value of Litecoins, you might earn anything from 50 cents to 10 dollars a day using only consumer-grade hardware.
But how do miners make profits? The more computing power they manage to accumulate, the more chances they have of solving the cryptographic puzzles. Once a miner manages to solve the puzzle, they receive a reward as well as a transaction fee.
As a cryptocurrency attracts more interest, mining becomes harder and the amount of coins received as a reward decreases. For example, when Bitcoin was first created, the reward for successful mining was 50 BTC. Now, the reward stands at 12.5 Bitcoins. This happened because the Bitcoin network is designed so that there can only be a total of 21 mln coins in circulation.
All of those factors make mining cryptocurrencies an extremely competitive arms race that rewards early adopters. However, depending on where you live, profits made from mining can be subject to taxation and Money Transmitting regulations. In the U.S., the FinCEN has issued a guidance, according to which mining of cryptocurrencies and exchanging them for flat currencies may be considered money transmitting. This means that miners might need to comply with special laws and regulations dealing with this type of activities.
If you really think about it, Bitcoin, as a decentralized network of peers that keep a consensus about accounts and balances, is more a currency than the numbers you see in your bank account. What are these numbers more than entries in a database - a database which can be changed by people you don't see and by rules you don't know?
Basically, cryptocurrencies are entries about token in decentralized consensus-databases. They are called Cryptocurrencies because the consensus-keeping process is secured by strong cryptography. Cryptocurrencies are built on cryptography. They are not secured by people or by trust, but by math. It is more probable that an asteroid falls on your house than that a bitcoin address is compromised.
Describing the properties of cryptocurrencies we need to separate between transactional and monetary properties. While most cryptocurrencies share a common set of properties, they are not carved in stone.
Transactional Cryptocurrency Properties
1. Irreversible - After confirmation, a transaction can't be reversed. By nobody. And nobody means nobody. Not you, not your bank, not the president of the United States, not Satoshi, not your miner. Nobody. If you send money, you send it. Period. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net.
2. Pseudonymous - Neither transactions nor accounts are connected to real-world identities. You receive Bitcoins on so-called addresses, which are randomly seeming chains of around 30 characters. While it is usually possible to analyze the transaction flow, it is not necessarily possible to connect the real-world identity of users with those addresses.
3. Fast and global - Transactions are propagated nearly instantly in the network and are confirmed in a couple of minutes. Since they happen in a global network of computers they are completely indifferent of your physical location. It doesn't matter if I send Bitcoin to my neighbor or to someone on the other side of the world.
4. Secure - Cryptocurrency funds are locked in a public key cryptography system. Only the owner of the private key can send cryptocurrency. Strong cryptography and the magic of big numbers make it impossible to break this scheme. A Bitcoin address is more secure than Fort Knox.
5. Permissionless - You don't have to ask anybody to use cryptocurrency. It's just a software that everybody can download for free. After you installed it, you can receive and send Bitcoins or other cryptocurrencies. No one can prevent you. There is no gatekeeper.
Monetary Cryptocurrency Properties
1. Controlled supply - Most cryptocurrencies limit the supply of the tokens. In Bitcoin, the supply decreases in time and will reach its final number sometime around the year 2140. All cryptocurrencies control the supply of the token by a schedule written in the code. This means the monetary supply of a cryptocurrency in every given moment in the future can roughly be calculated today. There is no surprise.
2. No debt but bearer - The Fiat-money on your bank account is created by debt, and the numbers, you see on your ledger represent nothing but debts. It's a system of IOU. Cryptocurrencies don't represent debts, they just represent themselves.
To understand the revolutionary impact of cryptocurrencies you need to consider both properties. Bitcoin as a permissionless, irreversible, and pseudonymous means of payment is an attack on the control of banks and governments over the monetary transactions of their citizens. You can't hinder someone to use Bitcoin, you can't prohibit someone to accept a payment, you can't undo a transaction.
As money with a limited, controlled supply that is not changeable by a government, a bank or any other central institution, cryptocurrencies attack the scope of the monetary policy. They take away the control central banks take on inflation or deflation by manipulating the monetary supply.
What Can You Do With Cryptocurrency
Accept As Payment
Cryptocurrencies are digital gold. Sound money that is secure from political influence. Money promises to preserve and increase its value over time. Cryptocurrencies are also a fast and comfortable means of payment with a worldwide scope, and they are private and anonymous enough to serve as a means of payment for black markets and any other outlawed economic activity.
If you happen to own a business and if you're looking for potential new customers, accepting cryptocurrencies as a form of payment may be a solution for you. The interest in cryptocurrencies has never been higher and it's only going to increase. Along with the growing interest, also grows the number of crypto-ATMs located around the world. Coin ATM Radar currently lists almost 1,800 ATMs in 58 countries.
First of all, you need to let your customers know that your business accepts crypto coins. Simply putting a sign by your cash register should do the trick. The payments can then be accepted using hardware terminals, touch screen apps or simple wallet addresses through QR codes.
There are many different services that you can use to be able to accept payments in cryptocurrencies. Popular services include Cryptonator, CoinGate and BitPay, with the latter only accepting Bitcoins.
In the U.S., Bitcoin and other cryptocurrencies have been recognized as a convertible virtual currency, which means accepting them as a form of payment is exactly the same as accepting cash, gold or gift cards.
For tax purposes, U.S. based businesses accepting cryptocurrencies need to record a reference of sales, amount received in a particular currency and the date of transaction. If sales taxes are payable, the amount due is calculated based on the average exchange rate at the time of sale.
Peer To Peer
Peer-to-Peer transfers occur when one person pays another person using a mobile device. The payment routes through an app that initiates, authenticates, and transfers funds.
In-Person purchases are initiated using a mobile device where the buyer and seller are together, usually in a retail location like a restaurant or mall.
Remote payments are made when a buyer purchases goods or services on their mobile device, but they are not physically present. This situation describes most online payments.
Many people believe that cryptocurrencies are the hottest investment opportunity currently available. Indeed, there are many stories of people becoming millionaires through their Bitcoin investments. Bitcoin is the most recognizable digital currency to date.
Ethereum, perhaps the second most valued cryptocurrency, has recorded the fastest rise a digital currency ever demonstrated. Since May 2016, its value increased by at least 2,700 percent. When it comes to all cryptocurrencies combined, their market cap soared by more than 10,000 percent since mid-2013.
However, it is worth noting that cryptocurrencies are high-risk investments. Their market value fluctuates like no other asset's. Moreover, it is partly unregulated, there is always a risk of them getting outlawed in certain jurisdictions and any cryptocurrency exchange can potentially get hacked.
If you decide to invest in cryptocurrencies, Bitcoin is obviously still the dominant one. However, its share in the crypto-market has quite dramatically fallen from 90 percent to just 40 percent. There are many options currently available, with some coins being privacy-focused, others being less open and decentralized than Bitcoin and some just outright copying it.
While it's very easy to buy Bitcoins, there are numerous exchanges in existence that trade in BTC, other cryptocurrencies aren't as easy to acquire. Although, this situation is slowly improving with major exchanges like Kraken, BitFinex, BitStamp and many others starting to sell Litecoin, Ethereum, Monero, Ripple and so on. There are also a few other different ways of being coin, for instance, you can trade face-to-face with a seller or use a Bitcoin ATM.
Once you bought your cryptocurrency, you need a way to store it. All major exchanges offer wallet services. But, while it might seem convenient, it's best if you store your assets in an offline wallet on your hard drive, or even invest in a hardware wallet. This is the most secure way of storing your coins and it gives you full control over your assets.
As with any other investment, you need to pay close attention to the cryptocurrencies' market value and to any news related to them.
Depending on a jurisdiction you live in, once you've made a profit or a loss investing in cryptocurrencies, you might need to include it in your tax report. In terms of taxation, cryptocurrencies are treated very differently from country to country. In the U.S., the Internal Revenue Service ruled that Bitcoins and other digital currencies are to be taxed as property, not currency. For investors, this means that accrued long-term gains and losses from cryptocurrency trading are taxed at each investor's applicable capital gains rate, which stands at a maximum of 15 percent.
In the past, trying to find a merchant that accepts cryptocurrency was extremely difficult, if not impossible. These days, however, the situation is completely different.
There are a lot of merchants, both online and offline, that accept Bitcoin as the form of payment. They range from massive online retailers like Overstock and Newegg to small local shops, bars and restaurants. Bitcoins can be used to pay for hotels, flights, jewelery, apps, computer parts and even a college degree.
Other digital currencies like Litecoin, Ripple, Ethereum and so on aren't accepted as widely just yet. Things are changing for the better though, with Apple having authorized at least 10 different cryptocurrencies as a viable form of payment on App Store.
Of course, users of cryptocurrencies other than Bitcoin can always exchange their coins for BTCs. Moreover, there are Gift Card selling websites. Through gift cards, you can essentially buy anything with a cryptocurrency.
Finally, there are marketplaces that only accept cryptocurrencies.
Selection Of Cryptocurrencies
Selection of Cryptocurrencies.
While Bitcoin remains by far the most famous cryptocurrency and most other cryptocurrencies have zero non-speculative impact, investors and users should keep an eye on several cryptocurrencies.Below are the most popular cryptocurrencies of today:
The one and only, the first and most famous cryptocurrency. Bitcoin serves as a digital gold standard in the whole cryptocurrency-industry, is used as a global means of payment and is the de-facto currency of cyber-crime like darknet markets or ransomware. After seven years in existence, Bitcoin's price has increased from zero to more than 650 Dollar, and its transaction volume reached more than 200.000 daily transactions.
The brainchild of young crypto-genius Vitalik Buterin has ascended to the second place in the hierarchy of cryptocurrencies. Other than Bitcoin its blockchain does not only validate a set of accounts and balances but of so-called states. This means that Ethereum can not only process transactions but complex contracts and programs.
This flexibility makes Ethereum the perfect instrument for blockchain -application. But it comes at a cost. After the Hack of the DAO, an Ethereum based smart contract, the developers decided to do a hard fork without consensus, which resulted in the emerge of Ethereum Classic. Besides this, there are several clones of Ethereum, and Ethereum itself is a host of several Tokens like DigixDAO and Augur. This makes Ethereum more a family of cryptocurrencies than a single currency.
While Ripple has a native cryptocurrency, XRP, it is more about a network to process IOUs than the cryptocurrency itself. XRP, the currency, doesn't serve as a medium to store and exchange value, but more as a token to protect the network against spam.
Ripple, unlike Bitcoin and Ethereum, has no mining since all the coins are already pre-mined. Ripple has found immense value in the financial space as a lot of banks have joined the Ripple network.
Litecoin was one of the first cryptocurrencies after Bitcoin and tagged as the silver to the digital gold bitcoin. Faster than bitcoin, with a larger amount of token and a new mining algorithm, Litecoin was a real innovation, perfectly tailored to be the smaller brother of bitcoin. "It facilitated the emerge of several other cryptocurrencies which used its codebase but made it, even more, lighter". Examples are Dogecoin or Feathercoin.
While Litecoin failed to find a real use case and lost its second place after bitcoin, it is still actively developed and traded and is hoarded as a backup if Bitcoin fails.
Monero is the most prominent example of the CryptoNight algorithm. This algorithm was invented to add the privacy features Bitcoin is missing. If you use Bitcoin, every transaction is documented in the blockchain and the trail of transactions can be followed. With the introduction of a concept called ring-signatures, the CryptoNight algorithm was able to cut through that trail.
The first implementation of CryptoNight, Bytecoin, was heavily premined and thus rejected by the community. Monero was the first non-premined clone of bytecoin and raised a lot of awareness. There are several other incarnations of cryptonote with their own little improvements, but none of it did ever achieve the same popularity as Monero.
Monero's popularity peaked in summer 2016 when some darknet markets decided to accept it as a currency. This resulted in a steady increase in the price, while the actual usage of Monero seems to remain disappointingly small.
Besides those, there are hundreds of cryptocurrencies of several families. Most of them are nothing more than attempts to reach investors and quickly make money, but a lot of them promise playgrounds to test innovations in cryptocurrency-technology.
Advantages And Disadvantages Of Cryptocurrency
Cryptocurrencies hold the promise of making it easier to transfer funds directly between two parties, without the need for a trusted third party like a bank or credit card company. These transfers are instead secured by the use of public keys and private keys and different forms of incentive systems, like Proof of Work or Proof of Stake.
In modern cryptocurrency systems, a user's "wallet," or account address, has a public key, while the private key is known only to the owner and is used to sign transactions. Fund transfers are completed with minimal processing fees, allowing users to avoid the steep fees charged by banks and financial institutions for wire transfers.
The semi-anonymous nature of cryptocurrency transactions makes them well, suited for a host of illegal activities, such as money laundering and tax evasion. However, cryptocurrency advocates often highly value their anonymity, citing benefits of privacy like protection for whistleblowers or activists living under repressive governments. Some cryptocurrencies are more private than others.
Bitcoin, for instance, is a relatively poor choice for conducting illegal business online, since the forensic analysis of the Bitcoin blockchain has helped authorities to arrest and prosecute criminals. More privacy-oriented coins do exist, however, such as Dash, Monero, or ZCash, which are far more difficult to trace.
The market of cryptocurrencies is fast and wild. Nearly every day new cryptocurrencies emerge, old die, early adopters get wealthy and investors lose money. Every cryptocurrency comes with a promise, mostly a big story to turn the world around. Few survive the first months, and most are pumped and dumped by speculators and live on as zombie coins until the last bagholder loses hope ever to see a return on his investment.
Markets are dirty. But this doesn't change the fact that cryptocurrencies are here to stay, and here to change the world. This is already happening. People all over the world buy Bitcoin to protect themselves against the devaluation of their national currency. Mostly in Asia, a vivid market for Bitcoin remittance has emerged, and the Bitcoin using darknets of cybercrime are flourishing. More and more companies discover the power of Smart Contracts or token on Ethereum, the first real-world application of blockchain technologies emerge.
The revolution is already happening. Institutional investors start to buy cryptocurrencies. Banks and governments realize that this invention has the potential to draw their control away. Cryptocurrencies change the world. Step by step. You can either stand beside and observe, or you can become part of history in the making.
