from this data shows that not always the price of bitcoin can be high, there must be a year that makes the price of bitcoin collapse and this year the price movements are almost the same as in 2014-2015 (prices tend to fall).
I do not think we should rely on past prices or past price movements because we can fall into error. for example someone may think that because last year the price went up from $ 1000 to $ 19000 and will happen again this year or other years, and that person will fall into error. For example, last year we had no regulations like this year. two years ago we had no regulations like this year. That's why we should not rely on past prices.
