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? 
Yes, not only are you cursed, most people sell prematurely, I think it is sometimes right to sell and get out of the coin, read a lot of books on trading
