Coinbase has fees for transfers and you can't sell Bitcoin with it. I use QuadrigaCX, their services is excellent and quick. In that exchange, in your account, there is wallet for Bitcoin, Bitcoin Cash, Litecoin and Ether, all separate, and you can fund with either of those, with CAD or USD. It's safe and secure. I transfer to there from Blocktrade and then to either my credit card (with very minimal fees) or my bank account (the no fee option). I've been with it since I've been on Steemit and I'm very satisfied with it thus far.

I'Ve since dropped my Coinbase account, it still exists as a backup, but I don't have anything in it anymore.

Otherwise, I have a Neo wallet for my Antshares and GAS tokens, which is something else altogether and was complicated to set up, so Frank did that for me.

Oh and Quadriga is free. You just need to validate your account with a picture of yourself holding ID, and a picture of your ID and of a proof of address. They checked mine within 2 days, and I had a question since I don't have a passport nor a driver's liscence, and they replied within 2 days, on a Sunday.

If you decide to check them out, don'T hesitate to reach out. You can also contact them directly, they'll reply quickly enough.
