maybe he is based on a four-year cycle, where from 2017 to 2021 there will be another bullrun. but I also think that there is no guarantee, it could happen sooner or later. but at least if we hold the main coin of course it will be safe to invest. a lot of analysis here and we can't blame one by one, the most important thing is that we believe in ourselves about what we are going to do
indeed there is no guarantee for predictions that are shared according to future market conditions.
Moreover, the crypto market can move very wildly without anyone being able to predict it correctly. 3 or 5 years I don't think the crypto market cycle can be described properly. This market moves with the trends created by investors and traders. the more crowded the market will be for the future of the market.
