your post was made in 2018. and now 2021 has even passed a significant coin price increase. Q1 2021 is one of the best coin points to date. so I think this season is a coin decline that maybe we can't predict when the price will experience a significant increase like Q1 2021
In general, it is difficult for everyone to predict the increase in the price of all coins, because it is also related to market conditions and trends that run every year, so predicting prices and market conditions is not easy for anyone, because the market often changes in seconds.
