Well, here in the US, I don't expect any problems, but I guess we'll find out soon. I mean, certainly I wouldn't be the first person to test Coinbase's $50,000 limit, right? And since they have already done KYC, it shouldn't be a problem, should it?
i tried to take out 40k via coinbase in december and failed. but the larger point is that even if coinbase does not fail, or you use local exchange, whatever, then trying to move the fiat thereafter is not necessarily going to work well. you may be better off spending btc.
