Am I reading this correctly that the team is now just Jens Peterssen and the whole Menze family has bailed?
If the project required a certain amount of money you should have set a minimum cap. You did not reach your imaginary minimum cap, which means a) people did not believe in your project and b) most of the team cannot be paid. Investors did not pay for a one man show.
IMHO this project is dead and buried and investors should be refunded.
Nice teamnya actually experienced in the trade domain, and in developing applications are also different. the success or failure of the project depends on people who are in it, we can just wait for her for token exchanger only.
