These experts are simply stating that the speculation behind cryptocurrencies is present because they likely believe that there is no real value backing them up- you are simply buying a line of computer code. Well, once they realize people are becoming as rich as them from this 'speculative mania' then they will think back to the time they made those comments lol take your profits as you go- 2018 gold rush is just about underway
@techblogger enjoying your posts and will continue to weigh in and comment what I think... thanks for sharing
