Let's review the story of BTC and mining:

Bitcoin mining was a global "gold rush" in the past, attracting many participants. From the good old days of PC CPU mining, to GPU mining machines, FPGA mining machines, and now ASIC chip machines, mining hardware has been constantly iterating. In this game, early miners witnessed the ups and downs of Bitcoin prices and the development of the mining industry.

On January 3, 2009, Bitcoin founder Satoshi Nakamoto personally created the first block, marking the birth of Bitcoin. At that time, Bitcoin mining was carried out through the CPU of an ordinary personal computer, with a computing power of about 20MHash/s. Few people participated in the early days. With a computer that can connect to the Internet and download a Bitcoin wallet, you can mine, which is very easy. For example, Sheldon in the American TV series "The Big Bang Theory" mined some Bitcoins seven years ago using Howard's old laptop. $BTC #比特币 #挖矿算力 #挖矿难度
