The problem is a catch 22, you cannot be stable until you gain volume and you cannot gain volume until you are stable.

Simply using a smart contract between two parties doesn't give the underlying coin stability, and it introduces the risk that one party ends up with an undervalued/overvalued coin. The average person will still earn in dollars, shop in dollars, pay tax in dollars and do accounts in dollars. The demand for crypto as a result will be restricted to speculators, criminals and (some) geeks. I cannot see stability anywhere on the horizon.
