I'm very annoyed that Coinbase is currently unavailable at the moment. I was going to transfer my Bitcoin to Coinbase, but I can't because of this. I have heard many others complain about this. Instead of waiting, I'm going to use Xapo.
I've used it before and liked it so I'll see how this goes. I liked Coinbase because you can add cards really easy and transfer to a bank account. I still like Coinbase, but it's very inconvenient, especially for people trading on that site.
