This is not about scam projects. This is about the projects which fail to raise enough funds due to what so ever reasons. When bounty hunters work for weeks and at the last moment project announces that they can no longer run it due to insufficient funds raised, its nothing but a waste of time and energy for us.
In my opinion, should project teams have enough fundings before they look for investors? What is called MVP is very important for the users to check for before investing.
MVP will ensure that even if funds are not raised as expected, it can be delayed but not dead.
From your point of view, what other points are there which projects and investors both look for?
