Don Tapscott, the father of the digital economy and chairman of the blockchain research institute, said in an interview recently that he is not a "bitcoin-rich". In terms of business applications and currency globalization, Don is more optimistic about the prospects of stable currency. It is believed that all stable currencies are likely to contribute to a global currency. Don does not believe that China's legal digital currency should try to become a global currency. The latter should be in the form of a global cryptocurrency that the Bank of England Governor Mark Carney has called for to replace the hegemony of the dollar. Don’s attitude towards supervision is very objective. On the one hand, he criticizes the prevailing government’s strict supervision of the blockchain with the certificate, and on the other hand, he clearly opposes “the central bank should not be involved in the blockchain”. Such a radical argument. In addition, he said that he is not optimistic or pessimistic about the future of the blockchain, and that the blockchain will not eradicate the problems we face, but it gives us an opportunity to make everything better.
