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.
This is why I'm buying a substantial amount of btc before my trading break rather than cashing everything out and buying back in the trend reversal - the risk of the two fiat transactions - cashing out and depositing back in, will outweigh the gain on the trade of whatever is left of the downtrend at this point. Who knows if... by that point maybe my bank will have put some block on bitcoin exchanges and I won't even be able to get back in as it's breaking out.
