Yeah, it's always a Panic seller on all Alt Coins. If they See red they will panic to sell their coins to prevent more loss. I think you cannot control it because they have a self-control and self-decision to do what they want.
This is a risk in crypto investment. when panic occurs the price will then go down. therefore you must adjust the existing conditions to the choices you will make. so always do research and analysis. as much as possible before panic happens you have determined the choice you made. panic selling or panic buying is a natural thing in the market.
