Bump. Anyone? Specifically interested in Gemini, but the others as well.
I haven't any experience of gemini, but BobLawblaw says it's the best he's found for found for wiring in/out money, although its support is shit.
If you are in the US, I recommend Gemini. Their support is complete and utter shit, but it's the simplest exchange I've found for wiring in/out money, once your accounts are properly linked and jumped through their AML/KYC hoops.
Coinbase is an even worse shit-show right now.
