I came to think about a speculative conspiracy theory. The BitLicense will allow banks to quickly accept and adopt bitcoins. And now the banksters are pancaking the bitcoin price so they can easily buy the majority of the bitcoin market (corner the market). And after that stunt the bitcoin price will skyrocket. Checkmate.
This is not true, however the opposite is true. The regulations will make the exchanges act more like banks. Banks will not be able to invest their own money into bitcoin as this would more or less be speculation which the banks are not able to do with their own money because of frank dodd regulations on bank capital.
In theory we could see banks start to accept bitcoin deposits and create bitcoin exchanges that compete with existing ones but I would doubt that they would attempt this and even if they did I don't see it catching on as most people who use/trade bitcoin are generally not fans of big banks.

http://en.wikipedia.org/wiki/Dodd%E2%80%93Frank_Wall_Street_Reform_and_Consumer_Protection_ActThe Dodd–Frank act seems to be about accountability and transparency, not about stopping banks from trading with currencies. Or?
And think about it: Will the average people trust having their bitcoins in a bank or in a MtGox? Most people would not be able to securely manage their own cold store, and would have their bitcoins in ordinary bank accounts.
