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 don't think it is your mistake , that happens normally in the cryptocurrencies market, you should learn to accept that, i think that isn't a good lesson for you .
