Wirex works (guess you have to wait in line).
They use Contis for their cardservices and virtual bank accounts. (cards: EUR, GBP, USD; accounts only GBP live for now)
Maximum balance on virtual account GBP 7,500; USD/EUR 8,000; however unlimited withdrawls (it seems).
The whole solution seems to fully under FCA/UK control.
Funding, via bank or bitcoin.
