Bitcoin is really a tool for fast money transfer in cyberspace. Electronic transactions will gradually replace traditional transactions, helping consumers and businesses significantly reduce time and transaction costs. Stimulate the development of the information technology industry and play an increasingly important role in the economy. Bitcoin transfers are very fast and because they are inaccessible, I think this makes them very popular. Bitcoin does not have high scalability. Bitcon is digital gold. Because bitcoin uses trnsactions out of the internet, it is very convenient and faster than bank transactions.
