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..
I think it's more of a missed opportunity than actually losing any money. You lost the chance to to get profit. There's great lesson here, and that's to always have faith in your coin specially if you've done a thorough research about it. All coins do have the potential to really moon which will give a greta profit.
