It is never a good thing to sell hastily.
It is never a good thing to sell below ICO price.
It is not also good to sell at exactly the ICO price.
There were times sold when i was not supposed to sell. Just because of the excitement of receiving tokens through bounty participation and perhaps through airdrop, i was eager to cash out.
Most of the times i did this, i always found out that i later ran at loss, not considering my effort and the time spent in promoting such project.
I could have also had 2x and sometimes 10x the ICO price, but impatience made me to loose the opportunity.
My last experience was on a token i received. Mentioning the name will be of no use, but for crypto enthusiasts to also learn from my mistake. Ever since then, i have learnt to hold and this has been profitable to me.
No matter how you got your token or coin, always try and be patient enough to hold until you are in profit.
Only those who fully understand the crypto market have a chance to be profitable. This is not easy or free money that you will receive after your task has done. You must have a tolerable patience to wait until such time the project will blossom into a profitable investment. Profits will not come once the token get listed in exchanges as this will dumps due to impatience investors and bounty hunters that can't wait the development. Don't get panic in every bad news, the price will hit the bottom but it will recover and will rise again. In the end, patience will prevail.
