Hahahaha good joke buddy. If you're buying an ICO shitcoin AFTER the presale, more often than not, you're just throwing money away. You should absolutely not divert serious amounts of funds into ICO coins after they've already been listed on exchanges. With that being said, non-ico shitcoins or shicoins currently in ico are still fair game.
It is the harsh truth about ICOs.
After initial phase of ICO when there is no hype anymore and pumping is done,
then it is you best chance to sell off every token and forget about this coin.
The best and quite recent example - Zcash - right after the end of ICO period was over price of 1 token was around $1300 for a few days.
And now Zcash is worth $30.
