There are 2 altcoin I know which implemented non volatile by equalizing the price with $1. USDT and USNBT.
Like @sweetdesirez said, you need more innovative ideas, I'm sure if you show good credibility, the people will trust and used in trading, no matter with the price, like bitcoin.
I haven't talked any specifics concerning my plan yet, just a general direction.

Yes, I am aware of Tether and I'm glad it exist. Perhaps I gave a wrong picture in my initial post (?) but I don't intend to create anything parallel to fiat currencies, but a new system.
