Yes off course the future is bright anyway because the time is great dimension for the bitcoin itself and that we already experienced since the year 2009 when bitcoin was first introduced into the market. The major developments will be done to bitcoin blockchain technology and this will include the scale up issues, blocks size and time of transaction. Off course they all are interrelated and can be vanished in no time! Thus more applications of bitcoin will be done and more investors will get attracted into the bitcoin itself. Thus until 2020 which is almost three years from now can alter the course of future really.
