> I don't see how kyc/aml applies to this particular stock over every single other ticker they will happily sell you? There's no difference, they aren't selling cryptocurrency here.
It's the equivalent of security theater. Do something conspicuous that they can spin as having done something about the problem. That serves their purpose regardless of whether it actually does any good or makes any sense.
On top of that, cryptocurrency kind of competes with banks, so they have an excuse to cause trouble for the competition.
