At the Libra hearing on the Facebook cryptocurrency project held by the US House Financial Services Committee, the committee's vice chairman and Congressman Patrick McHenry said in a concluding remark that we are talking about a possible use of one or two billion users. Private currency. This is a breathtaking public discussion about Facebook that reflects the concerns of congressional policymakers because they don't understand digital currency. Because politicians want to kill it when they don't understand innovation. But you can't kill the cryptocurrency. I hope that there will not be much ridicule in 30 years. This hearing will be good because we have a deeper understanding now.
