It doesn't matter what I believe, it's what I experienced and observed. For example, I knew a couple who lost their money via fraudulent debit card transactions and bank did piss all to investigate - and I understand its hard and bank is not motivated much. By using a credit card for example fraudsters would've spent bank's money and my friends would not be responsible for such transactions. Now if they used crypto they would be in the same position and there wouldn't even be an authority to ask to investigate (how convenient). I am not saying that people are not getting ripped by corp - just by probability many people are. But I don't see "crypto" as the answer to the problems I know about. What specific problem crypto solves in payments?
