It depends on the state you are in. Signet bank has its very own cryptocoin and many small banks are adopting cryptocurrencies as long as the local laws allow for it. It is only the big corrupt banks that are making a fuss about adopting crypto. They can't stand the thought of a future where they are not the center of everyday monetary life of people..
Silvergate Bank underpins plenty of crypto businesses in the USA. I'm not sure whether they welcome personal business from crypto fans. Lots of people seem to use credit unions. Regardless of where you settle you're better off treating any account you conduct crypto business through as disposable. It's not sensible to risk your main account by exposing it to your regular bank.
I heard of both of them but I am yet to see anyone being able to use either of these banks to set up something personal. And I guess that really depends on what you want to do, which was not specified here.
Can either of you verify if either of these banks or some other bank actually allows commercial applications, like stores and such?
