I actually think that is the perfect analogy. Will there be a widely adopted cryptocurrency in the future? Maybe. But will one of the current options be that winner? Again maybe but seems unlikely to me. Do I have the ability to pick that winner with confidence? Absolutely not. It all looks like garbage to me.
I don’t even get the mining process to be honest. How is that different than a currency where anyone can print more bills? And what happens when all the coins have been mined? Will people want to keep buying smaller and smaller fractions of coins?
The whole thing just sounds stupid to me on a conceptual level. Then add in things like people getting locked out of their wallets, joke coins blowing up in value, rug pulls, etc. “I’m out”.
