Wouldn't the best course of action be to step away from this anyway? If so many important questions remain unanswered there is a reason for it. And it's not a good reason I guess from an investor's point of view.
That sounds like a pretty good solution. Unfortunately, the people that are most vocal here have already invested in the project.
I'm one of them.
Do you think your money is lost? Maybe some of those talking here are accounts of the team to get this going? Or is there a chance that this is a serious project?
