Read the white paper, watch the development team, the real use of the token, also watch traffic on Alexa, pay attention to the project Manager.
Thank you for the advice and I would like to be supplemented by your advice
Reading the whitepaper is very necessary to see if their roadmap is properly designed, check carefully if the whitepaper is not there or do not follow the roadmap, it is ICO scam.
Next up is the development team, make sure they are on the big forums and you have enough information about them
The most important thing is probably the community, check how many they have folloewd on Facebook, TW, Telegram
