There are myriad groups building various projects, some private and some public. The best ones are generally private, as the profit motive is involved.
I'm mildly skeptical, mildly hopeful. Wish all those clever folks the best from me.
Heh. It is indeed helpful to keep things on the private side when the motivation is to profit...especially when the design is to profit by ripping people off.
Developments out of the Bitcoin community generally are far and away the most closed source I've been mildly involved with and also the most scam infested. But the 'free market' tends to correct for such things...and we are down to $2.36/BTC as I tap this out.
