Depends on who the 7-11 cashier is. If they are really smart, they would gladly take your crypto and pay for your items with their fiat. You are not going to get big places using it first. You are going to get little places using it first. The Amazon's and 7-11's and Walmart's of the world will come later. And trust me, they will come. There's a natural tipping point apparently, where when 5% of the world population uses something, the other 95% generally soon follow, because it's more useful. Crypto has already hit that 5% mark.
