alt Hacker NewsVery impressed at net cost. I used to run a small ecom business targeting total prices in the range of $3-10. At $3, payment processing is nearly 11-12% of costs, which is absurd, more if you amortize the occasional chargeback/fraud. Lightning can do it for <<0.1% net cost even at the low end, which is incredible. There are plenty of these kinds of vendors on eBay, Aliexpress etc that would be willing to adopt with a bit of help.
For whoever posted, your cost calculator should be first thing on the page, and you "How we calculated this number" link is broken

I would guess the price for payment processing drops tremendously when you don't need to handle fraud or chargebacks at all. It's for sure worse for consumers but I do think it has its place (for example adult content that has huge chargeback risk or straight up blocked by other processors).
Monero is even cheaper and more useful as cadh because it's private. Anyone can see Bitcoin history and where the user got their coins.
lightning is a pain to set up, you have to open a channel and keep funding it - so if we are talking about small amounts these costs should definitely be added to your calculation. or you use lightning via an exchange - but that again kinda defeats the purpose of bitcoin. in fact all of this could probably be achieved much simpler by just using a stablecoin on tron, solana or one of the ether chains and forget about the whole lightning sending and bitcoin hedging. I doubt you can get lower transaction costs end-to-end staying on btc.
