They are trying to prevent a digital bank run. Just like they prevent people from taking too much cash out from a branch at once to prevent cash liquidity issues they now want to prevent how much money you can send to bitcoin exchanges so they can stop bleeding deposits.

The reason they are blocking money from being sent to bitcoin exchanges is because they know bitcoin is a direct alternative to a bank account. Bitcoin is a swiss bank in your pocket. They know that instead of a physical bank run where people run for their cash this time around it will be a digital bank run where people run to send their money out to turn it into bitcoin because bitcoin is the most liquid store of value, it can be stored on a piece of paper and sent around the world instantly.

I am telling you guys, get your stack locked in now and move it to cold storage otherwise when you are ready to buy you wont be able to. First they will limit how much you can send to a bitcoin exchange, then they will spout some reason like financial stability to block you from sending money to bitcoin exchanges all together, then exchanges will get shut down all together once bitcoin is blamed for the coming global banking crisis.

Dont wait until its too late, lock in your stack now and move it to cold storage.
