I saw a project and on that project I did not see the team and DEV from the project. however they use Escrow with good positive trust, can it be a determinant that the project will not be scam?
There still a chance for this project to be scam and maybe they are just trying to get the trust of the investors. if you're a bounty hunter then the payment for you is sure, and you don't have to worry about but if you plan to invest then having an escrow is still not a sign of this project will be good in the future, you must still review their whole project.
This is the point why mass fails to stick. If there is no working product then it is useless to expect something good from projects in my opinion. Investor confidence is down for these type of reasons and escrow is not going to cover the gaps by project managers.
