What Is a Cryptocurrency

Cryptocurrency, or digital currency is an exchange medium. It uses some tools, such as cryptography, for transactions securing and their verification. Cryptography used as well to control the process of creation of new units of some kind of cryptocurrency.

Basically, cryptocurrency is nothing but a software, or an entry in the database that cannot be changed till some conditions are not fulfilled.

Cryptocurrency History

In the 90-ies there were attempts to create cryptocurrencies. Flooz, DigiCash and Beenz are those that mover further than the others. Though they did not exist too long, as there were too many cases of fraud, frictions among competitors, and other problems.

The most interesting thing though was that all of them used the TPP approach. It means, behind each digital currency there was a company that was securing ad facilitating the transactions.

Though as failure was followed one after another, the creation of a new cryptocurrency was seen as a loss of time and energy, and money, of course.

Bitcoin Birth

In 2009, a programmer or a group of programmers, under a pseudonym Satoshi Nakamoto, registered a website. That was the start of bitcoin history.

At first, it was announced as a Peer-to-Peer Electronic Cash System. It looked like a file sharing system. It did not have any servers, no controlling authority, the system was absolutely decentralized.

The biggest issue that the system had to solve is the option of double-spending. Traditionally, the Trusted Third Party had to solve it, it is a server that records all transactions and basically, controls the system.

Though bitcoin does it via the Blockchain. The Blockchain is a public ledger for all transactions that are happening in the network. Everybody can get access to it and see the transactions.

A transaction is the data of the sender`s and the recipient`s wallet addresses and the amount of the transferred coins. Then, this data is signed off by a private key of the sender. The transaction is available in the network, but first, it has to be confirmed.

Within the network, it can be done by miners only. They make the transaction as legitimate and spread it in the blockchain. Transactions are also recorded in the database. After confirmation, the transaction becomes irreversible, the miner gets his reward and a fee.

Cryptocurrency is called like this because all is ensured with cryptography.
All the above mentioned makes all third parties not needed.

One more currency that is reliable for investing is Ethereum. Since the start of 2016, its price grew for 2,700 %. The investment profit is evident.

Though you shall remember that investing in cryptocurrencies is risky as well. They are characterized by a very high volatility level. Moreover, they are not regulated. This is an advantage but an additional risk as well. Any cryptocurrency exchange can be hacked, which is also an additional risk.

One of the most interesting things is that the puzzles are becoming more and more complicated, as the number of miners is growing. speaking simply, the more people are trying to mine, the more complicated the process becomes.
Many people became rich from bitcoin. Earlier, mining was possible just with one computer. Now though, to mine, you shall buy industry hardware. That is not cheap, plus, add huge bills for electricity, as it consumes lots of energy.
Nowadays, the best cryptocurrencies are considered to be Litecoin, Dogecoins and Feathercions, especially if we speak about investors-beginners. Mining Litecoin, for example, you can make up to 10 dollars per day, and this is just with a normal consumer hardware. This fact, that huge initial investments are not needed, makes less popular currencies more attractive.

The more computing power the miner accumulates, the more chances he gets to solve the crypto-puzzle. If he manages to solve it, he gets a transaction fee and a reward – bitcoins.

With bitcoin introduction, a completely new concept of money was created. Decentralized and uncontrolled money, which were perceived as a threat to traditional financial system. Money that doesn’t exist in physical form.

All that caused many concerns of regulators from all the world, as it is very helpful for illegal activities, such as making payments for drugs, terrorism funding. And what about money laundering and tax evasion? Cryptocurrency looks like perfect for that.

For now, bitcoin is illegal just in some countries, such as Bangladesh, Ecuador, Bolivia, Kyrgyzstan, Vietnam. In other countries, the regulation may vary, though miners and investors can be calm: their activities are legal.
