There's no point in them accepting it to just swap it for fiat though.

It's also infinitely more important that the demand for Bitcoin as payment comes from those who produce, not the middle men who sell.

If manufacturers (basically just China) and farmers (all over the world) demand payment in Bitcoin then that's all we need to kick off a global Bitcoin standard.

Want stuff? You need to have Bitcoin. Want food? You need to have Bitcoin. Merchants will want Bitcoin because they need it to pay for the goods they are selling. Likewise, employees will demand their employer pays in Bitcoin because they need it for food etc.
