Your money also won't be dropping to below its half value in a few years time if it was in a bank. At the end of the day, it's a matter of preference. Yes investing and using Bitcoin as your storage is a good choice, but that doesn't mean that everyone who stores their money on banks are idiots. They just prefer safety more than anything I suppose.

And granted putting your money on a bank that'd close down in your generation sounds like a bad choice originally in the first place ngl. Granted it is possible, but it's highly unlikely no? I mean at least comparing it to Bitcoin dumping every few years, that's more probable to happen than a well known bank closing down. And Bitcoin being, well, Bitcoin, would only ever work if people knew how to make it so. Most of the time, they don't.
