Just being on Stacker.News is a great way to get exposure to how powerful lightning network is...we're paying each other to make great content over the internet, independent of where we are on the globe or what borders are between us. Borderless, frictionless commerce with next to zero fees is a real game changer.
For comparison, take a look at the fees that VISA charges its merchants (who pass it onto their customers). Looking through the table of fees to merchants, I don't see a single option that is less than $0.10 plus a percentage fee (0.05% - 3.15%). On the consumer side, this debt is charged an additional ~10-25% interest for those that carry a balance.
For a merchant, there is only a choice between three providers: VISA, MasterCard, American Express. On Lightning, there are 16,000 possible providers that are competing to process your transactions. Currently, there are 46 offers on Magma alone that can provide the same payment processing service at an average price of 2.27% APR.
Lightning is an open market, traditional payment methods are closed markets running an oligopoly.
