Hard to avoid, here is some tips.
3 Ways to Identify an ICO Scam:
1. The Developers Are Anonymous
The first and most blatant sign of an ICO scam is that the tokens developers are anonymous or otherwise-unknown.
2. The Token Does Not Have a Clear Use Case
Another sign of an ICO scam is that the developers are unable to clearly articulate a valid use case for the token.
3. The Whitepaper Sets Unrealistic Goals
If the whitepaper sets an unrealistic development schedule, it either means the developers are using deceptive tactics to attract token buyers or they lack the necessary experience to give a sensible scope to the project. Either way, this does not bode well for the success of the project and its corresponding token.
