Understandable move and might turn out to be good in the mid-term (in a non-speculative way)
Since when banks decide what people can buy with their credit cards? Is bitcoin illegal?
It might be their credit card but it's still the banks money, even though I believe in Bitcoin and recommend investing to people I wouldn't give them my own money to do it.
Right on point. I only see a problem when they forbid to use a pre-paid credit-card for such a purpose. Though I don't know if something like that is a thing in the US.
It's rather common in Germany, but the mentality here is very different.
Prepaid credit card can be an easy and speedy way out from btc to fiat.
