"But at present, digital money is also driven mainly by investment, in order to get the return on investment, not to use it as a currency." As early as May 2014, Yang Zhiyuan had invested in the special currency payment platform BitPay.
This year, the price of bitcoin has risen crazily. It was less than $1000 at the beginning of the year, but it broke through $10000 in November 28th. Today, the price of bitcoin is again high, up to $15000.
Although Yang Zhiyuan see bitcoin's future prospects, but there are also people who are skeptical of it. For example, Goldman's CEO Lloyd Blankfein (Lloyd Blankfein) earlier this month said bitcoin is "cheating tool."
