Senator Cynthia Lummis and Congressman Warren Davidson talk at the Bitcoin 2021 conference in Miami. "If we don't defend private wallets, someone will try to outlaw them," Davidson says. Bitcoin is a "fantastic asset to dovetail with the US dollar," according to LummIs. On Saturday, the event will run for a second day, with speakers and debates scheduled for Sunday and Monday. The Bitcoin Foundation and the Bitcoin.com Foundation, a venture-backed venture capital business, are hosting the event.
