Sir Richard Branson has revealed further support for bitcoin as a functional, albeit volatile, currency.

Asked in an interview with Bloomberg News whether the cryptocurrency will eventually work, the Virgin Group billionaire said that bitcoin is already working:

While Branson admitted that bitcoin remains volatile, he added that this is not necessarily a bad thing. “It is quite volatile, but in volatility people can make money,” he said.

The entrepreneur also reflected on Virgin Galactic’s decision to start accepting bitcoin payments last November:

Earlier this year Branson said that Virgin Galactic had already received payment in bitcoin from six different customers.

Virgin Galactic has been testing much of its hardware in recent months, but Branson admits building the infrastructure for commercial spaceflights has been hard. He told Bloomberg that Virgin’s rockets are still undergoing flight tests, but the rest of the infrastructure is already ready.

“Early next year we will finally be up and away,” said Branson.

Virgin’s goal is to fly tourists to space in suborbital flights, using its SpaceShipTwo craft.

In addition to Virgin Galactic’s decision to accept bitcoin payments, Branson has also made his mark in the wider bitcoin industry by investing in BitPay.

Branson took part in a $30m Series A funding round for the payment processor, along with Index Ventures, AME Cloud Ventures, Founders Fund, RRE Ventures and others. At the time it was the largest-ever funding round for a bitcoin company.
