If a bull market like what happened in 2017 is what we are hoping, i believe we would have it at least in 2020. 2017 is very bullish because many projects was started and what i believe will happen by 2020 is that many of this projects will become useful as a service that they were intended to not just as a way of making profits. It will be the time when mass adoption will take place and people will buy tokens not for it to trade but for it to be used in the way it was intended.
