I think that panic sales will be after Bitcoin falls below $ 3000. After most likely he will either start to grow again, because then to purchase whales, or go even lower but will begin to rise as purchase whales.
We already saw a panic market and a lot of people sold their coins in that market which caused Bitcoin to reach to that lower price from now I do not think that the price will drop any more so we cannot say that it will drop below $3000. From now we have to expect the rise in the price.
