you should be asking if the ico is legit or no .
well here are some hints i could remember
1- if the team is -unknown- its 100 % to pass since it will turn to scam in most cases
2- if they have no telegram group just a - channel- then your airdrop / bounty / ico may turn to scam .. i mean why the team will avoid contact with their investors ??
3- check if they have been listed in the most popular ico analysis website and if they have - 3 note in most of them that mean they are not good enough ( i saw icos with 4 )
4- check the documents like whitepaper and road map
5 - team bro its important dont just look if they have team photos but if they really exist ? since Facebook has live video most of the ceo of the icos are using it to contact with their investors
there are much more sign to reduce the chance of getting scammed but ofc you cant be so sure .
note that even if the ico is legit
it can fail hard and that will lead to another question which is how to define if the project is a good investment or it will just suck my money lmao ?! well thats for you to know just search in the forum and you will find some great answers
