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.
I've thought about and debated this in my mind as well. I'm in the same boat, whether to sell a large chunk of btc on the next run up (and the next, and so on, ad infinitum) vs. just taking out a monthly/bi-monthly withdrawal to cover living expenses as time goes on, etc. I haven't had issues with my bank so far, but I've heard others have depending on their bank (Chase seems to be one culprit) and the specific amount that the bank 'flags' as suspicious. For those of us who want to continue to increase our btc holdings while the bubbles last, being able to sell large amounts of btc at the bubble tops is kind of a necessity.
