The demand for bitcoin will speak for its future and at the rate it is goingwe can say that it has a future. Some countries are even regulating because they already realized the tremendous potential and effect of bitcoin in their economy.
There is no one out of us who can predict this thing that what will happen in the coming few months. But if we make a look at the graph of the market price of bitcoin since the time it was introduced to this world, then well observe this thing that the market price has increased most of the times. I can really hope that it will keep on increasing in the comings days too just like the way it increased in the past.
I found no reason to worry about the future existence of bitcoin. Stay calm and optimistic with bitcoin. I do not know why people worry about the future of bitcoin. Currently they are the best digital coins and no other currency can pose a threat to its existence
