Thanks for the information. But do you have a list of campaign managers who are not scammers.??
Just stick with well-known campaign managers.
If you saw a newbie manager without any previous work before, then you can turn on your caution signal.
You can also see whether the campaign has escrow or not, obviously escrow are not going to be used on ICO campaigns, but on regular Signature Campaign it should give you a relief that your coins are stored on third party in case the campaign ran away without paying their participants.
