I don't know if I am cursed or something. If I sell a coin now from airdrop/bounty few days later that coins increases much that you will regret selling. If I hold a coin from airdrop/bounty again that coins price decreases much that you will regret not selling right away. I'm confused now whenever I sell the price increases and when I hold the price decreases. Am I cursed? 
in my opinion it is better to hold back if there is a price decline in the crypto market, we cannot make mistakes in selling bitcoin or altcoin because if we make a mistake we will lose a lot of money. we have to hold the altcoins until the market price is more expensive or the sale price when the ICO, if the market price is already worth ICO or more than the ICO price then sell the coins we have before the price drops again.
