There is no definite method to find good project except by comparing facts and figure, check how serious they are and if their project seems real in any way
Actually there are some ways to find out if that's really a good project but we can only speculate in the beginning but we don't know where it is heading.
A good project can turn into a bad project if one part of the team starts to act shady. It will cause ruckus not only the team but to the community that support that ICO/altcoin.
