I know there's at least one cattle ranch taking coin. So.... supply and demand. If there should eventually be a significant number of food trucks taking bitcoin, it's more likely their suppliers will. It all snowballs, or branches out... whatever you want to call it. Customers service end-business which takes coin, ranch services end-business, farm services ranch, and now the bakery has the option of a supplier taking coin, too. Assuming the end-business isn't immediately converting coin, they may be particularly interested in being able to buy their needed supplies for coin - in which case, more BTC customers = more coin = higher likelihood of trying to find suppliers taking BTC.
Exactly.
The fun part will be seeing how fast it all happens and at what moment business realize they don't need dollars anymore to sustain their business or daily life. Then the volatility will disappear because people can just stick to bitcoins. Not everyone will be out to day trade btc to dollars even if they can make a profit, just like most folks don't go trading fiat currencies every day.
The key is retail acceptance. this is the best chance to close the circle. I am trying to signup shops nar NYC now.
