Since the beginning of human civilization, people have been using coins to complete mutual transactions. In spite of different times, there are direct commodity exchange traditions or barter systems in different regions, but for thousands of years the civilized society has been using any kind of currency for transactions. Mainly the money became the currency for the convenience of the transaction. Gold and silver from cowrie, ivory to gem and pearls - Many things have been used as coins. However, since the last century, the currency of the currency became the currency of the currency. Since the discovery of the computer, digital currency has been taking place in the economy in the last few decades. There is no physical form like digital currency paper or other currency, and it exists only in the computer or in the virtual world. In our daily life, we are dealing with internet banking or mobile banking that is basically digital currency. In the trend of this evolution of the currency, the head of this decade became a new concept -

Cryptocurrency (cryptocurrency) or cryptomputation is a special type of digital currency that can be used by computer to carry out transactions using secret cryptography or cryptography. To get money from ATMs such as PIN numbers or entering your Facebook password such as password, make sure that this secret codecript is accurate. A typical form of the cryptomerium digital currency. It is also considered a special form of alternate currency. This cryptomputer became the most discussed topic in the world of economics in a little over a decade. And behind these discussions, the world's first cryptomorphic 'Bitkayen'

Bitcoin starts on August 18, 2008, the day that bitcoin.org is the domain registration of a website. In November of that year, a white paper named Satoshi Nakamoto was published, titled Bitcoin: A peer-to-peer Electronic Cash System. However, this 'Satoshi Nakamoto' is not known to any person, organization or party. It is assumed that this is an alias and who is behind it and who is still unknown. Many people thought that the discovery of this Bitcoin as a protest against the failure of the government and the banks during the 2008 global financial crisis; Because Bitcoin is a currency that has no central control organization like other currencies. However, starting in 2008, the first transaction of Bitcoin was completed on 3 January 2009. In this first transaction, computer programmer Hal Finney will get 10 bitcoins from Satoshi Nakamoto to download the Bitcoin program first.

Bitcoin Digital Ledger is created through this transaction. This laser is usually a computer laser, similar to a used office laser diagram, where there is a calculation of all transactions completed by Bitcoin. This laser has a digital copy of all Bitcoin user computers, which is regularly updated. In order to complete a transaction, the transaction is transmitted to many computers where the computer automatically checks if the transaction is valid. The secret cryptography or cryptography that was mentioned earlier came in handy for this test. If a sufficient number of computers mark the transaction as valid, then it gets validation and the transaction is updated on all computers in the world that have Bitcoin lasers. This digital laser has been named Blockchain.

In order to properly protect this block link, the cryptography is used to deal with the secret codes for transactions. This requires the use of computer processing power. Users are using computers to solve these codes and keep the blockchain effective. Each time the users of the solution computer to solve the blockchain get the new Bitcoin. Thus, the new Bitcoin and the Bitcoin supply continued to grow in the same way. Thus 'mining' is the process of making new bitkayes; Which means in Bengal means 'lift from mine'.

However, there are both advantages and disadvantages of Bitcoin as per the new system. Since Bitcoin is a cryptococoncy, its complete ownership depends on the file that is stored on your computer. Your personal file tells you that your Wallet is the one that holds out the bitcoins you own. If you delete the file for any reason, all your bitcoins will also be windy. Again, anyone who knows the secret key of your personal file's cryptography can use your bitcakes without any hesitation. Since there is no central control agency, there is no place for remedy or justice in these cases.

Bitcoin starts with when the price of bittacquena is more than 10 times between 2016 and 2017. Of course, many people are also seeing evil intentions in this sudden emergence. Many economists believe that this is a special technique to cheat a Ponzi scheme or a piram scheme. However, the World Bank has already rejected such claims. Others say that the price of bitcoin is based on rumor, which is called speculative bubble. In such a case, it can make many users vulnerable to a large dip in any time. Two major programmers of Beitben have made it aware of this issue. Moreover, after the same kind of increase, such doubts are at once unreal
