According to an article by Coinbase CEO Zeeshan Firuz, published today 14 March, Coinbase has become the first cryptocurrence exchange to open a UK bank account and use the Fast Payment Plan (FPS).

The agreement between Barclays and Sybase was helped by the fact that Sikkines received an e-Money license from Britain's Financial Conduct Authority this week.
