As usual we can see from the whitepaper, website and the teams that are behind the project, if everything is good, that's mean the great campaign and will be potential for succes and do not forget to look at people's judgment, how much interest they are in a bounty and how many support and participate in an ico project.beside that also check who is manager of bounty, i prefer to manager who has high rank and much trusts  because it will can be trusted.
