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 have quite same experience like you too. It was a token of a good ICO. I thought the token price will falling, therefore i sold it.
But later i found out that the token price was going up about 10x and i still didnt know what is the cause.
