Scammers isn't the least of it. The system they have designed and executed is ludicrously insecure and falls to even the most basic of flaws. It's unlikely that it will ever be able to achieve consensus given the endless stream of crashes and logic errors, like being able to send yourself a negative balance (thus, infinite money) or crashing every node in the network by sending a block header with a nonce of zero. The sheer quantity of security bugs and undefined behavior in the two clients attempting to act in bit-for-bit identical ways in two different languages is quite alarming.

I'd bet against it ever getting to try it's consensus given that their launch is now going to be completely centralized (ie, it can't stand up on it's own let alone with malicious attackers, so it's going to be remotely controlled by the developers for now). Will they ever remove the crutch and risk everything crumbling? Seems very doubtful.
