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.
looking at history is a good thing. and analyzing the charts and the history doesn't have to mean you rely on them. besides it usually depends on what the majority of the market thinks. if they think this year should repeat last year's rise from $1k to $20k then it will happen because they will buy it up. and if they think just because last time the bear market lasted long, it should also last long this time too then it certainly will last long.... as you can see it is being prolonged now because most people thought 6 months of bear market is not enough and it should be equally long as last time.
