Yep they should not panic about the price of bitcoin, if they don't believe the potential of bitcoin then let them sell their bitcoin, only believers who earn profit.
The thing with panic sellers is that they will always re-enter the market, which means that we won't ever be freed from them unless they decide to quit, but that's highly unlikely with how addicting crypto is.
On the other hand, if these panic sellers weren't selling, we wouldn't be able to buy at current levels, so we have to give them their due credits for that. Most long term hodlers won't ever say no to discounted coins.
Enjoy every aspect of this market, because institutions will take it over and then it will become much more of a developed asset with plenty of liquidity. In other words, the market will become boring for most people.
