There is a way for you to pay someone in bitcoin, like there is a way for you to pay someone with your credit card but is there a way for you to automatically pay for your Spotify subscription, or car insurance WITH bitcoin?
There still needs to be a signature every time, unless it’s built on some level like the lightening network is built.
It’s a layer 2 for bitcoin that holds BTC in its ecosystem and therefore it makes fewer actual bitcoin transactions which makes subscriptions possible. Perhaps it can be built using the Lightening Network.
