I do not think it can honestly because the bitcoin itself has a good future, but not so good at all, the banks are still too big these days and I think its also not gonna change in the future.
The banks are one of the most powerful things on the global globe in my eyes, it has such a lot power, it can really control all the people in the whole globe.

I think that access already exists or will soon appear to all the wallets in the world

Big deals are made in bitcoin, so I do not consider it dangerous
