i thought this was gonna be an actual thankful post to coinbase , i've personally never used coinbase. However , i think its your UK'S bank fault and not coinbase's fault.
Oh don't get me wrong absolutely my UK bank is at fault, which is why I didn't verify my UK bank account in the first place by making a deposit. I was not even planning to sell the bitcoins for pounds (essentially cashing out), I wanted to sell some for euroes (which I did about a month ago) and when price drops buy back in.
My point is when the price was flat for the most part over Feb I was able to sell my bitcoins in exchange for euroes to coinbase. It's just a little funny how when the price started to go up pretty quick that when I tried again my ability was blocked.
