The lack of transparency from Bitcoin’s founders has attracted some criticism, but its open source nature means anyone can audit the code. It is a brilliantly conceived idea to allow users to power the peer-to-peer payment network themselves, providing control and freedom for consumers.
Bitcoins aren’t yet formally recognized by governments as a currency but with some regulation I hope that it will become more widely accepted. A few years ago many people had doubts about whether Virgin Galactic would ever get off the ground. Now we have gone supersonic, are a long way along the testing process, and are looking forward to launching commercial space travel.
