I think the lack of confidence is due to governments and regulations. Consumers would have confidence if they didn't have to worry about some regulation that ends up to where they can't access their funds. Or go through more KYC/AML policies, funds being put on hold, basically if governments are trying to make crypto like fiat, then not much of a point using crypto if it's the same as fiat. We want to get away from the current system. We are not going to fix things if we are just going to set things up the same way.
