That's exactly what a shit coin does, they list and most scam coin started falling more in price and way below the ico price, the first thing you need to consider is that who are the ones selling at such price if not the dev. Don't be too worried that's what shit coin do
Investors throw away their coins followed by bounty hunters. in essence they were not sure of their coins, and the team did not provide certainty about their project.
I see most ICOs like that. but some projects managed to reach ico prices even more. I still remember that Dentacoin reached a great price after Iico.
Exceptions don't prove the rule in the investing and ICO prices are not in favour of the investor after listing on the exchanges. Good prices are not a big deal for smart investors and they look for the reliability on every project. The atmosphere in the project and team are more important for me.
