Does Coinbase works okay with Barclays Bank (UK) for fiat deposit/withdrawal?

Yep, no problem. I don't think this was ever actually an issue. Probably just an issue with the individual person verifying themselves. There's a "refer a friend link" which gives me $10 worth of Bitcoin and you $10 of Bitcoin (about 7 quid) of6you use my referral link: https://www.coinbase.com/join/archib_dm6?src=android-link

Once you're in they do a "learn to earn" thing where you watch a video and answer a few questions and you get about £20 (in totoal) of some alt coins. I've just shared this link so someone may beat you to it, but worth a shot. I only have 1 invite left on eos and 2 on xlm.
