No matter what banks do, they're entirely entering an entirely opposite territory of where they belong and since they couldn't do anything about it, the least they could do is impose an unimaginable fees so that they could somehow do something about it.

Yes, they do want to profit off something from it and other intention is just like the usual incidents you hear like managing their user's PKs and like the usual freezing their wallets when something that they don't like happens. As much as I appreciate their "warm" welcome with crypto, I would not buy any forms of crypto through their means.

About the question of if they should be in game, everyone has the access to crypto anyways so there's not much we could do if banks want to be part of it.
