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 ?

    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.

    • walletdrainer a day ago

      Technically you’d transfer a larger chunk of bitcoin and receive change

      • rkomorn a day ago

        Technically how? In a way that isn't abstract to either parties in the transaction?

        • landgenoot a day 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 25 minutes 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 a day ago

      with lightning you can send a satoshi.

      • littlecranky67 21 hours 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 20 hours ago

          If one bitcoin is worth $10 million then 1 millionth of a bitcoin is still $10.

          • littlecranky67 20 hours 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.

            • immibis 19 hours ago

              To reiterate and paraphrase: "we need more coffee shops to accept bitcoin" "but it's not divisible enough" "that's fine because we don't need coffee shops to accept bitcoin"

              • littlecranky67 12 hours ago

                Well to be fair, Lightning IS bitcoin - and inevitably tied to it. It is just a different protocol, or a different mean of accounting and transferring ownership of bitcoin.

                Just imagine Gold was used as money, but you quickly realize that weighing and dividing gold is cumbersome. So someone creates a layer 2, prints green paper bills in arbitrary denominations and that very someone guarantees you can exchange those green paper bills at a fixed rates for ounces of gold. You exchange green paper bills, the green paper bills have value, but the underlying asset still is gold. Until that someone decided no longer to do the exchange to gold for those green sheets of paper, and basically performed the first rug-pull in history. That is where bitcoin steps in, as its decentralization guarantees there is no such rug-pull. And lightning is the green bills that can be exchanged for the underlying bitcoin anytime, without relying on the promise of a third party.

            The important detail being missed here is that the smallest unit is 0.00000001 bitcoin, i.e. one hundred millionth of a bitcoin.

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