I think bitcoin will be more expensive in the future, and more often it will be used as an asset to store money.
I don't think we'll see bitcoin being used as money to buy things in supermarkets. More convenient digital currencies will be used in the future.
Bitcoin is existing in this world for many years and many rich investor now is engaging themselves in bitcoin and other cryptocurrency so it has a chance that bitcoin can also used as currency on some store like supermarket and even restaurants will surely accept it.
