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?

This is the market, it is unpredictable, you are now caught in such a bad wave and can not get out of it, that's get the opposite results, just a little effort, luck and everything will turn out!
