The team of an ICO is responsible for the poor marketing management, bad organisation and the lack of funds. You cannot blame bounty hunters or the lack of investors, because if the team is going to scam us, we can only spread this news on this forum.
The scam ICOs and the failed ICOs are two different things. The scam ICO team members will try their best to show their project as the best and if anyone lose their money in that then the promoters and the investors are responsible for that while the failed ICOs are those which have non experienced team and for that failure the team is responsible.
