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 still believe you sell more higher than the initial $2 you bought it. If you sell higher than the price you bought it, you still make profit and no need to regret. You think if you wait for 2 weeks, you will make 80k and you will still regret that if you wait one year you would have make 500k. So need to regret, in crypto everybody have a entry point and exit point, you have to plan this when you are investing in ico and trading crypto.
