Okay, neither of those entities can ultimately pass any laws. Laws are entirely in the hands of the government, so as far as regulations go, Wall Street and banks barely have a say.
It will depend on your country if your government wants to "stop" Bitcoin, but overall, in the global scale, the outlook is pretty positive. If you live in the US, which I assume because you mentioned Wall Street, then you have nothing to worry about.
If it could be happened so countries would have been banned bitcoin now but bitcoin is not in control of countries because bitcoin is completely decentralized. Counties can just impose restrictions on exchanges and not they can do more than this. There are so many ways for people to access to bitcoin frequently.
If someone draws rules for bitcoin so I don’t think so that they would be able to implement the rules in real sense and at the end they would realize the fact about decentralization feature of bitcoin.
