Thank goodness that the merchants that I do deals with do not force me to pay with cryptocurrency.
Cryptocurrency transactions require high trust in the sense that they cannot be refunded, but they also require low trust in the sense that the vendor cannot possibly steal any more money than what you sign them.
With an open season of friendly / chargeback fraud, customer lies, refund tricks, etc which customers keep doing every day and so on which too many of that and Amazon will ban your account and they should.
