1. Has this projects team doxxed themselves, meaning are they public facing and out front with who the founders are, this makes them not always but most of the time more accountable if they want to keep a reputation with keeping up promises made with the project.
2. Do they have previous project experience, how did that go?
3. Research tools look at what blockchain they will be on, have there already been projects like this one how did they do?
4.How long are you willing to wait to see if they live up to their whitepaper and roadmap? Is this a flip or hold?
5.How much do you want to invest in this project and in the market overall how much are you wanting to diversify into new tech and its long term potential?
Bonus here for you, many articles have been written about do they have twitter followers, do they have active discord and telegram communities. *You can buy followers and bots in all social platforms* @followeraudit
While I do check a project does have a website and has socials, I tend to lean toward discord and check to see they have an active team that answers questions before feeling ok with picking up more than one of anything but thats me.
