A while ago i went all in ZClassic and bought about 365 Coins when the price was about 2$ per coin, but i decided to sell a couple of days after.
Two weeks later zclassic mooned and i could make about 80k now.
i learned my lesson in the hard way..
Don't worry, you didn't lose anything - you missed an opportunity which is totally different thing. There were many people who lost half of their investments because they've sold at the bottom just before rebound. And that was a hard pill to swallow.
