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.
i believe everything is more or less a risk, because different tokens differ from one another, how ?
if you do not sell hastily, token could dump and never rise again.
if you wait to sell above ico price, you may end up selling at a ridiculous low rate. we can only hope our research and assumptions will lead us to making the right and proper decisions.
All these lessons you can learn BEFORE you have lost all your money. It is the main mistake of all newbies - they firstly invest, and only then try understand what they do.
