I am not sure how strongly you believe projects isn't scam and not involved with money. Are not they selling their coin/token on exchange? So from where came this coin/token on exchange. Obviously from team, the of course fund is going to team as well. Since team members/co-founder involved with scam previously how we believe him that he will not scam or he will not skip after sell his token/coin.

For your info, if just listed on exchange doesn't prove legitimate of any project's. Coin/token might be drop or delisted any time when team will skip or inactive. So there is huge chances of scam in my opinion.
