Adoption as a hedge against fiat debasement, primarily. FTX wasn’t a bank BTW, it was a shady exchange that mostly laundered money and stole customers’ funds. It was more analogous to a precious metal dealer like JM Bulion or similar, except run by criminals.

The purpose of crypto isn’t to integrate with the existing system anyway. The purpose is to provide a parallel system that isn’t subject to the kind of manipulation present in the legacy system. Unfortunately, crypto has become completely overrun with scammers and charlatans just looking to take advantage of rubes. The fundamental principals of Bitcoin are still intact in the code and network though, and IMO will win out simply because it is incorruptible and indestructible. The legacy system seems to have decided the same, and is currently adopting a ‘if you can’t beat em, join em’ attitude by pushing for ETF products to offer bitcoin to their customers though more traditional means.

I don’t expect my post to change anyone’s mind, but I would encourage anyone reading to look into why bitcoin has crashed multiple times and come roaring back each time.
