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.
Which is not a good idea at the moment since a few miners have most of the hash rate and it is impossible to go against them due to the high resources they have and the incredible cheap electricity costs they have because most of them are in China and there is no way to compete with them.
