Investing in a good project is very difficult because it is difficult to distinguish between a real project and a scam, but the easiest thing I do is research the whitepaper, then review from ICO sites and see discussions on discord or telegram.
Researching whitepaper and website quality is first step to do before researching another indicator, but i dont agree to take review from ICO sites as one of the consideration, since many shilling and overhype as review there.
