> Find Bitcoin-Friendly Coffee Shops – We Need Submissions I'll bite: If i own a bitcoin, evaluated today at, let's say, 100 k$, and then pay with it for a coffee, how much bitcoin will i have left ? Do they give change ?

  No change. A latte costs $100k if you pay with bitcoin.

  If this is a serious question... you'll pay a (small) fraction of a bitcoin, just like you'd pay a fraction (or some units and a fraction) of whatever currency. Just as when you pay with a card or online, you just pay the amount. There's no change.

    Technically you’d transfer a larger chunk of bitcoin and receive change
    - rkomorn 1y ago
      Technically how? In a way that isn't abstract to either parties in the transaction?
      - landgenoot 1y ago
        Basically you split your bitcoin and send one part to the recipient and one part back to yourself.

        Basically, that is my question: What is the lowest bit of a bitcoin ? For Euro, or other curency is 1/100 aka cent.
        rkomorn 1y ago
        1 sat (Satoshi) is 1/100000000 bitcoin, so at the moment it's around 0,001 euro. And then you get millisatoshis that can be used on the lightning network, but I've not dealt with that directly myself.

  bitcoin is divisible to 1M places.
  - cranberryturkey 1y ago
    with lightning you can send a satoshi.
    - littlecranky67 1y ago
      you can even send millisatoshis (but depends on the node configuration, often it is declined). But lightning nodes do take milisats as fees.

    So divisible to $0.10, and if it goes to the moon like hodlers insist, divisible to $1, then $10, then $100, then $1000.

      No one hundred millionth of a bitcoin
      - slau 1y ago
        If one bitcoin is worth $10 million then 1 millionth of a bitcoin is still $10.
        littlecranky67 1y ago
        There is no problem with that, as Bitcoin itself will never reach the transaction volume of regular cash - it couldn't even handle that given the number of transactions (nor does it make sense to store your coffee payment on any given day for a lifetime in the blockchain). Thats where layer 2 solution such as Lightning come into play - for everyday, more privacy-friendly smaller transactions that are not put on the blockchain. And on Layer 2, you can go even smaller in denominations.

There is already a lot of data about this in OpenStreetMap: https://wiki.openstreetmap.org/wiki/Bitcoin https://wiki.openstreetmap.org/wiki/Bitcoin
