Bitcoin is a brand new thing. Bitcoin, like the Internet, has a brand-new underlying technology, operating principle and upper application, which has never been seen in history. Telling ordinary people what Bitcoin is is as difficult as telling people in the 1980s what the Internet is.

Bitcoin (BTC for short) is a kind of digital currency, with a total amount of 2 1 10,000, which has the same characteristics as the Internet, such as decentralization, globalization and anonymity. Moving Bitcoin to the other side of the world is as simple as sending an email, with low cost and no restrictions. Bitcoin is therefore used in cross-border trade, payment, remittance and other fields.

Due to its broad prospects and huge imagination, the price of Bitcoin has been rising continuously since its birth in 2009. At 20 1 1, the price of bitcoin reached 1, and at 20 1200, it exceeded the price of 1 ounce of gold, and it has the reputation of "digital gold" ().
