If you can be patient better dont do panic sell. It cause the price at the market more down. Ussualy it just the big investor's play to make the price down. As we know if many people sell the asset then the price of that coin goes down. It's a market rule that more coin in the market make the price more cheap, also more scarce the coin that people looking for make the price more expensive.
Smart investor always wait this opportunity to buy a coin in a cheap price. Then sell again in high price. If you dont want lose from this kind of investor, you better keep you asset and sell it when it already give you enough profit.
