Coinbase is the exchange that's given me the most headaches and trouble when it comes to depositing and withdrawing. They asked me tons of questions and really try to limit my activities, including holding onto my money on their exchange. Because of this, I wouldn't put any amount of FIAT/crypto through︀ them.
Kraken on the other hand has never given me these problems (knocks on︁ wood).
