    Bitcoin isn’t good for making little purchases, firstly because it takes so long to get confirmations, if each block is 10 minutes and you need like 3 blocks to consider it confirmed that’s 30 minutes. But that ties into the second issue which is that you probably don’t want millions of tiny transactions on the Blockchain, you want them processed off-chain and then settled in bulk (to the Blockchain) periodically as a single transaction.

      Bitcoin is great for little transactions if you use the lightning network. Sending on the lightning network means instant payments with no confirmation required and absolutely tiny fees. And the only thing that shows up on the blockchain is the transactions to initially start using lightning network and to take your coins back off the lightning network. Transactions made over the lightning network aren’t recorded anywhere other than maybe by the people transacting.

        i got back into bitcoin recently and decided to move the contents of my old wallet to a new SegWit one and look into using lightning.

        To open a lightning channel i have to stake £170 up front though which is crazy, how are people in poorer countries supposed to do that?

        or even here. poverty is on the rise, a lot of people are living hand to mouth and just having that kind of money lying around isnt a thing.

        i like the idea of bitcoin but i worry it doesn’t scale well.

        Add to that that virtually nowhere accepts it. The value of bitcoin comes from its use as a currency. if it doesn’t have that then it’s entirely speculation.

        oh well, i have £2k in there and i’m not turning it back into fiat. I’ll spend it if i can or ride it all the way to 0 if that’s the way it goes

        “Bitcoin is great if you don’t use the block chain”

        That’s what you just said. So why even use it in the first place?

          the lightning network still uses the blockchain, just less. it’s acts like an immutable public bar tab you can’t default on. once you have spent enough with another person that it is worth them conducting the transaction on chain then it does it. usually when fees are low too.

          That is an extremely simplified explanation of how it works though, it is more complex than that.

          IIRC, a deposit is made by two parties to create a lightning network channel that’s enough to cover all transactions (kinda like a multi-sig escrow), and both parties have to sign-off on their balances after every transaction (the last balance signed by both parties is the only valid state). I think most people would use a custodial wallet where the custodian already has channels set up, and this would require trust in the custodian. Lightning networks didn’t exist, and wasn’t fully spec’d out the last time I looked into it though.

      That’s the same way as the economic system works though

      Each bank and creditor keeps track of if what they owe each other and then they settle the balancebetween them periodically (depends on the country)

      If assume you could do something similar with bitcoin, but you would need an overlay
