Too good to be a scam
Why do you think it is scam?
Because you haven't detailed anything about the protocol or how it's going to work. Demonstrate your ability through screen recordings of the client working properly.
Ok, some more project details to be stolen :-) in update. As I said before we have only very early team-alphas. But we work hard.
If you're basing your code on Bitcoin or any altcoin, then you're bound to operate under an open source license anyway. No one can steal something that's free.
Of course. When it's working prototype - source will be opened.
