The CEO of Virgin Group, Richard Branson, is serious about Bitcoin — so serious, in fact, that he's inviting some of the top cryptocurrency experts to a conference held on Necker Island, his private island in the British Virgin Islands.

The Block Chain Summit, as the conference is called, is held from May 25 to May 28. It includes a long list of banking, finance and business experts, including Arie Y. Levy Cohen, the managing director at Morgan Stanley; Barry Silbert, founder of Digital Currency Group; Lars Rasmussen, head of Facebook Search; and Brock Pierce, the chairman of Bitcoin Foundation.

According to the event's website, the agenda includes "highlighting critical issues and solutions and to lay out the framework for a world where the humankind is fully benefiting from the amazing technology behind the Blockchain." The blockchain, one of the fundamental technologies behind Bitcoin, is is a public ledger that records all Bitcoin transactions.

Strictly speaking, Blockchain Summit is not Branson's event; as Fusion notes, Branson is listed as its host, but he had no role in selecting the guests or curating the event.

Yet Branson is one of the biggest advocates for Bitcoin, letting Virgin Galactic travelers pay with the digital currency in 2013. He's also an investor in Bitcoin payment processing company BitPay and has publicly expressed his belief that "Bitcoin is working."

After its price plummeted to below $200 in early 2015, Bitcoin has seen good days and bad ones. When Coinbase started the first regulated U.S. exchange, some of the Bitcoin faithful had high hopes. In April, though, Bitcoin exchange Buttercoin shut its doors due to lack of funding.
