Donations to tranny-killing stalker sites hardly drives the kind of adoption that crypto speculators are expecting. You're talking about crypto supplanting credit cards and payment processors. This is a solved problem, and crypto doesn't solve it better. In fact, outside of libertarian fantasy fulfillment, it's worse in every way. BTW, Null still takes fiat.
So, debt. But debt is OK as long as it's not backed by fiat I guess? And just as with crypto payments, what problem does DeFi solve? Why does the average person need DeFi?
I pay zero interest on credit cards because I pay my bills in full every month. I even get paid to use my credit cards though cash back and bonuses. Why bother having to buy crypto to use as collateral for a loan when I don't need to? I haven't seen any crypto-backed loans for lower rates than I can get through a line of credit or margin from a broker.
