Before joining an ICO project, you should see the overview of that project. See Whitepaper, team, price of tokens, links, and information that are clearly public, ICO rating indicators are appreciated by the community to avoid fake teams.
All of this true and before I joining ICO before Im always looking for that and first I look is the white paper and other information to make sure it is safe but even Im checking it ny money still lose because the scammer are smart so I decided to become smarter than them so I did not invest to ICO last year until now but Im back again once I see ICO are good to invest again.
