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.
Yes I agree that the prices have some pattern on ups and downs. But really that pattern was not being programmed. The only thing they can rely is on the supply and demand of the cryptocurrency, which determines their ups and downs.
