Are cryptocurrencies about to go mainstream?

Last week Barclays’ CEO for personal and corporate banking, Ashok Vaswani, revealed the lender had opened discussions with UK regulators about adopting digital currencies.
“We have been talking to a couple of fintechs [financial technology companies] and have actually gone with the fintechs to the FCA [the Financial Conduct Authority, the UK regulator] to talk about how we could bring the equivalent of bitcoin, not necessarily bitcoin, but cryptocurrencies into play,” Vaswani told CNBC at a conference in Copenhagen, Denmark.
