I have mentioned this before, and i will again.
Just follow instructions and ALWAYS ASK QUESTIONS.
** The Team
Are they real people?
Do they have an experience that is relevant to the project that is verifiable?
** The Technology
Are the project developers open to dialogue? open to the public ??
Are they forthcoming or are they evasive? do they dodge questions from the public ??
Are responses specific or do the parties involved speak in generalities?
** The Token
How will the tokens be used, by whom and are there any indications of support coming from the market?
At what stage the project is currently in can also be very useful ??
Is the project in the idea stage, development stage or perhaps the project has already been launched?
How will the token be used in the network and is it even necessary?
MORE IMPORTANTLY, read their whitepaper. and do extreme research.
