It will be a good news if this token will be listed soon after the ico token sales. Yeah, if they will be listed easily then it can make the price of token increase high.
It's true that some investors that got the token with huge discount could choose to sell their token after ICO to gain some low profit specially if the token get listed only on those small exchanges, Having that said, No one can know if the price will go up or down, you should be ready to any scenario, because this is how the market works.
Yeah, that's a good point if I were the investor I will reasearch and review more about the project whom I will invest too. And also talk to people what are their opinions.
