Op, maybe you should share a link to this story. To those who do not know, Cash App has integrated BTC into their system a long time ago, as way back as 2018. You can buy BTC and you can also sell BTC for USD in-app. You can also send and receive BTC on-chain in Cash App, it's not a new feature.

So, i don't know what op is talking about, but since BTC is adopted in Cash App, then you could always use it to pay bills, provided the recipient accepts BTC on-chain.
