I checked OP post history and it seems like he had some terrible experiences with exchanges, at least from his perspective. That's probably why he wants to stick with what usually works for him, in this case stock exchange. But as others have mentioned, you're not buying Bitcoin with these products. If your goal is to own Bitcoin (I assume so looking at his post history) and if you can't find a good exchange to work with, you can try P2P. It will probably be a bit expensive and needs some trial and error, but you'll get your Bitcoin in the end.

Anyway, other than Coinbase, what other exchanges have you tried OP?
