PANews reported on May 4 that according to Cryptonews , BitMEX co-founder Arthur Hayes recently said that although the US government currently holds about 198,000 bitcoins (worth more than $ 18 billion), it is unlikely to increase its bitcoin reserves through direct purchases due to two major factors. One is the pressure of national debt, and the other is the public's stereotype of Bitcoin investors (the so-called "Bitcoin bros" ). Hayes believes that this negative stereotype will affect the decision-making of policymakers.
