I would say that everything comes with pros and cons. By online banking, we are able to comfortable store our money on bank account and withdraw cash anytime we wish, so we don't have to store all the money at house, pay comfortably and avoid issues, send & receive money in seconds. But it has the evil side: We aren't really insured and if a bank or the government wish, they can do whatever they want and shock the population. They can freeze our accounts, they can limit withdrawals as that happened in Greece.
Is crypto an alternative? Sure, but people aren't ready to use crypto as an alternative that will be a great escape. The majority of people think that they'll move on crypto and use crypto exchanges but that's not an alternative, that's like getting eaten by shark instead of lion, does that matter? Anyway, you are eaten alive.

Crypto would be an alternative if people use offline wallets to store their money instead of traditional centralized crypto exchanges. That's very risky too cause you can't predict the price but at least no one can steal a thing from you.
I don't believe bitcoin will experience this kind of support because people trust banks, seeing posts on this forum can't help you to make the right conclusion because there is a different picture on this forum compared to real life.

Every day I start to think that Anarchy can be a better alternative because the governments suck very much but then I realize that people always form social bonds and then the government or similar structure is formed again.
