Bitcoin, in my opinons has had it up and downs, but who supplies us bitcoin? Faucets can only supply so much before it gets closed down. So that's not a big supplier. Working for bitcoin has declined. I used to make videos and earn bitcoins. But that site has closed down like every other sites or faucets. So who supplies us bitcoins nowadays? Tell us please!
Not sure if you are asking who pays people bitcoins or who produces bitcoins. The latter is a stupid one if you are implying that. Bitcoins are mined, so if you want to get your hands on bitcoins without relying on anyone else then go mine bitcoins yourself.
I don't quite understand how people even ask questions like this. A simple search on YouTube or Wikipedia will tell you most of the things you need to know to get started using Bitcoin. Not hating, just saying!
