Listing of coins before ICO ends- "The implications "

[Pamela1966]

Lately I've come across few projects that list their coins on decentralized exchange before the end of ICO which I think it's like a sabotage to the efforts of investors and those supporting the project in one way or another because those that have the coins sell below ICO price.
I want forum members to share their views about this,  is it professional or an attempt at exit scam?
