I remember in january 2018 Bitcoin hit up to around 17K, not 19K. I also think the same thing if look at history, but history will not repeat itself in the same pattern, it will be different. But this is not the beginning of the bear market, and it has entered the middle of it I believe, to be honest I am not someone who is an expert on this but that is the truth.
I agree that every movement pattern will be different every year, it will be very difficult for Bitcoin to hit the low in the bear market last 2018 but maybe $15k might be the lowest price in the next bear market but no guarantee it will be reached or even lower. I wonder that when the market is down people are too sensitive to judge the market at the lowest price.
