The devs have walked away with or investment

This project doesn't seem to lift off without the right people and i can tell you this aren't the right people for the job.
No they have not. Gamebet is a big project and takes time to make.
But they say June 1st for their new UI to come but that time has come and gone.

It looks as if GameBet gives empty promises too what I have seen of them so far.

This is not how a company, if serious, should display itself to the shareholders let alone to the public.
