There is no their money. It's all debt they play around with, which is something that the system here allows them to do. With debt, they expose others to debt, resulting in more debt -- it's debt all the way through. The only thing here is that while crypto still isn't properly regulated, these banks can continue to play this dirty game. It's nothing more than manipulation by abusing their status in the financial world at cost of the less knowledgeable people. Let them try that again when this market is completely regulated when we're a year or two further in time, they'll surely regret it, the bastards they are. People should end this by ditching them. Why stay with a bank that doesn't care about you and doesn't allow you to spend your own money the way you want?
The system doesn't allow them for anything. They are the system, or at least a part of it. Without the banks there would be no government, at least not in their current state. The banks are loaning money to the government to finance their war machines and idiotic moves (wall on the border with Mexico comes to mind) and the governments are there to bail out banks if they get in trouble. Correction, you, the taxpayer will have to bail out the banks, the government would be bankrupt long ago if not for you, slaves.
