Ups and downs.

Banks limiting their clients freedom to ourchase reinforce the crypto message there shiuld not be intermediary or centralized power that dictates what’s right or wrong.

I don’t think that bank thinks avout their client but only their own interests.
In the credit card model, banks wish late payers, they make crazy interests in any money loan that way. Banning the purchase of crypto assets is long part of a bigger strategy scheme to protect their power.
