There is possibility of bitcoin to be currency of future that can be used as a tool transaction. Because see function and progress at this time so rapidly.
Don't hype it too much, the progress is good but it is not enough to replace the current system and only bitcoin will be considered as money in the future. The thing is bitcoin was not created to be a primary money but only as a tool to help us with a faster and a more transparent transaction.
Sure, Bitcoin look like as a tool help us can send money fast and with low fee, but I not think it can become to currency, it look like as Digital Cash or Virtual Cash - can't replace USD or other currency on the world's
