As per my own opinion the bitcoin will play a major role for us in the future. It will become a monetary unit a form of exchange in the future.
Bitcoin create a chance for people to do transaction that can't be done with ordinary fiat so it's possible that bitcoin demand still remain high in the future.
Some country may still forbid bitcoin usage because it can be use for criminal purpose like corruption, money laundry , ransom , etc
i think that bitcoin will have a really great impact on the economy in the future because bitcoin will only grow larger. And i think that bitcoin will become famous.
And maybe a lot of people will use it so i think that bitcoin is really good to hold.
