    What if I want to buy a cheese sandwich today with BTC?

    A cheese sandwich can remain the same fixed price in dollars for years, with only the relatively slow change in actual value due to inflation.

    I’ve seen BTC swing 10% in 24 hours. Does the cheese-sandwich-maker have to look up the rate this instant and calculate a spot price for me?

    Will they have more or less dollars at the end of the day, when they need to pay their bills and buy more cheese from their suppliers?

    “Just buy cheese from someone who takes BTC”, doesn’t help, it just kicks the can further down the road.

    “Just add a bit of a buffer in the price to take fluctuations into account”, means that I go buy a cheese sandwich with dollars from next door because it’s 50 cents cheaper for the same thing.

    As an investment vehicle, BTC is doing hot laps of the track (with occasional accidents), but until its volatility issues are sorted and it becomes “boring”, it’s not going anywhere as an actual currency.

      Welcome to currency exchanges.

      If you want to buy a sandwich in Indian Rupees… you either find someone selling sandwiches for Indian Rupees, or you have to exchange them to whatever the seller will accept (USD? CAD? AUD? EUR?..)

      Yes, FOREX has some swings, it’s not for everyone. Bitcoin may swing more or less than other currencies, depending on the day.

      Does the cheese-sandwich-maker have to look up the rate this instant and calculate a spot price for me?

      If you travel around, you’ll find countries where sellers do exactly that: they pull out a smartphone, check the spot price, add some margin, and tell you the price in USD for whatever you’re trying to buy.

      Alternatively, you can swipe a credit card that will do all of that automatically. BTW, there are BTC backed credit cards too.

      buy cheese from someone who takes BTC […] just kicks the can further down the road.

      That’s how money works: you kick it all the way around the street, over and over, changing from can, to stone, to ball, to… etc. Those who manage to start with a can and end up with a Lambo, win. Those who end up with a single grain of sand, lose.
