Bitcoin is a virtual currency, a P2P digital currency, and peer-to-peer transmission means a decentralized payment system.

The concept of Bitcoin was first put forward by Satoshi Nakamoto in 29. According to Satoshi Nakamoto's ideas, the open source software and the p>P2P network built on it were designed and released.

Unlike most currencies, Bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations according to a specific algorithm. Compared with

Special currency economy, it uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transactions, and uses the design of cryptology to ensure the security of all links in currency circulation. The decentralized nature of P2P and the algorithm itself can ensure that the currency cannot be manipulated artificially by

making a large number of bitcoins. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This

also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between Bitcoin and other virtual currencies is that its total quantity is very limited and it is extremely scarce. The monetary system once had no more than 1.5 million in four years, and then the total number will be permanently limited to 21 million.

bitcoin can be cashed and converted into the currencies of most countries. Users can use Bitcoin to buy some virtual goods, which is

better than clothes, hats and equipment in online games. As long as someone accepts it, they can also use Bitcoin to buy real-life goods

Simply speaking, Bitcoin is a bit like Tencent's Q coins, which can be used to buy exchange items and recharge others. But unlike Q coins, Bitcoin is decentralized, and it doesn't need Tencent. Anyone can download Bitcoin wallet software to receive other people's transfers freely. Moreover, everyone involved in this system is keeping accounts synchronously, and it has very powerful science and technology to ensure security.

Bitcoin, like stocks or futures, is now regarded as the subject of speculation. On the Bitcoin exchange, there are a lot of swap transactions between special currency and legal currency every day, and the total amount of transactions far exceeds the amount needed to actually buy goods with Bitcoin.
