In my opinion cryptocurrency have patterns to learn. When it will raise and when it will goes down. You can see the history of the chart and make a analysis on it. For example, the price of one or some coin raised up in the end of year. When at Q1 the price start goes down. This thing can happen again in the next year. But maybe in different price.
It is possible, as you invest in cryptocurrencies, that you need a speculative head, and over the years of investment you will know the process and the method. It simply takes time for you to get to know and understand the BTC system
