In 2008, the Bitcoin white paper was released by Satoshi Nakamoto, which signified that the ownership of personal assets had started to transfer from an untrusted third party to the individual himself. Due to the strong correlation of BTC and other cryptocurrencies with finance, the industry was full of speculation, fraud, Ponzi, and other scams in the early days. But after more than a decade of social experiments, the progress of the industry is obvious: from mining with early personal computers, to mining with professional mining machines. And finally, everyone works together to dig through the mining pool and then distribute the reward according to the hashrate.
