No major problems so far. Weaknesses I realized:

1. Extra long fiat deposit/withdrawal times (with the exception of card payments, which don't take much time, at least according to my experience with small amounts)

2. No stop-loss options; so you either have to close your positions before going to bed, or lose sleep over it in a volatile market.

Other than that my experience has been pretty good. Coin transfers are fine, phone app is very convenient.

Overall, a good exchange
