2020n is not so far, and yet is very big in crypto world. Many things can happen, who knows,
i believe in BTC this can surprise us all, we could proudly say we are pioneers.
Considering the scarcity alone, with only 21 million coins ever in existence, then it should rise as something that is in demand but low supply would. Great possibilities of significant upward movement by 2020.
There are really some great possibilities that bitcoin can be big in 2020 its just user need to invite more users and companies must find bitcoin as useful as possible.
