Since blockchain technology, virtual currency together with digital wallets will reign in the future, Bitcoin will still be Bitcoin in several years since we are towards cashless society. It can also be use as mode of payments anywhere and everywhere, and that its goal.
I think the biggest change in Bitcoin a few years later is the price. Now I bravely predict that the price of Bitcoin will become one digit again after a few years.
Think about the excitement that Bitcoin can be used to pay in life in the future, but wait a minute, I think this possibility is very small.
