Frankly speaking, we do not know if by year 2020 is the best year for cryptoholders. A lot of things could happen every year price can climb or price can be low. But thinking to be positive could be help of the future of crypto.
Don't you think that after 2 years, crypto-currencies can either be very expensive or even can cease to exist. I hope we will see the first option as I have invested in crypto currencies is a large sum. I think many will support me in opinion, that to make predictions for 2020 it is useless.
