WOW... now you guys are saying you are not in control of the money...
4k will not make your project any better so you guys should not spend other people hard earned money...
Whatever you did, it did not work, so now is too late to be point fingers now. It is time to wrap up and learn from your mistakes...
Admit that you guys somehow you blew it, pay back the people who trusted on the project and move on...
There is no shame on it, you are much more experienced today than a few weeks back.
You should be proud of it, at least you tried.

When you take others people property it does not matter if it is:
0.0000001
0.3777
or
100000.000000 btc
it is going to hunt you forever, every time you look in the mirror you going to which you could go back and change the outcome. What goes around comes around...
Thinks about it...

Peace.
