Well, transactions settle with finality in seconds or minutes and cost pennies. Success rate is much higher, and failure is funds never left your account. So whatever it's held together with, which generally seems to be cryptography, mostly works.

You, ah...you know that "finality" is bad in a system that needs to transact money, right?

Fraud exists. (You should know. The cryptocurrency universe is mostly that.) But more importantly, judges exist, and they do not give a single sweet damn that you say it "cannot be reversed".

(And a hearty LOL at "costs pennies". Ethereum gas fees yesterday, on the say you posted this, averaged eight bucks in actual-money terms. I can send a wire cheaper than that.)
