Herman Gref, former Russian economic minister and current CEO of the Russian Federal Savings Bank, said in an interview recently that he had briefly touched Bitcoin and used some bitcoins to buy shirts and even lost some encryption assets and encrypted wallets. He said, "This is a casino, and I am not a player. Bitcoin is a tool to promote transactions, but it is not an investment tool. Digital currency has no future, because the country will never allow this to weaken its power. Decentralization. As early as 2018, Gref has stated that no country will accept a decentralized monetary ecosystem in the next 10 years.
