I think the price of bitcoin at the moment the price drops very much not as you mentioned, the highest price of bitcoin is up to $ 20k and now the price is falling so deep like this I think this is the most severe decline in bitcoin prices.
I think that price fall already dropped at $6000 range few months back but after that it keeps bump and dump at the range with different price swing range but certainly stick with that range only of about $6000- $7000,But still the price drop is normal in bitcoin and it happened many times since the creation of bitcoin so don't be afraid to hold your coins for long term.
