We have no guarentees that bitcoin will be next future money we all know that maybe one day bitcoin will gone but i hope bitcoin will stay years from now.
I'm not sure if Bitcoin is the future of money but I think Bitcoin will be allowed to use all over the world but still can't replace the paper money. But who could tell? Maybe someday, Bitcoin gained more potential to become the future of money.
I think bitcoin is the real future money but not in the very near future, it will take a time because there is lot of issue facing bitcoin in the real money market in which the banks are the top of the list. so may other issue are also there such as people that are not trusting bitcoin now. But it does not matter because an year ago the trust and popularity of bitcoin was low while now it is double it mean it generate trust and popularity to itself. through this way bitcoin can be a real money of the future.
