The best advantage of bitcoin is that it is digital. The future of money will be a digital money so I think bitcoin will go up as time goes by. It is never to late to start investing in bitcoins. I would suggest that as much as possible study bitcoins and if you know that you want to take the risk in investing, then it is the right time.
