One of the banks told Huobi it is going to close their accounts in 1 week's time. Huobi acknowledged and it still has a few more banks working with it.
The question is what will happen in the next few days? Will it stop at 1 bank or will there be more to come?
Of course they will all dry up eventually - it would be entirely pointless of China to only tell a handful of banks to stop dealing with bitcoin sites leaving plenty of other banks available. They would either go after none of them, or all of them. Anything else is pointless.
Don't forget the National Australian Bank will close all bitcoin related accounts in May.
