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!
Mined your own bitcoin
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.
He asking who is the supplier. Bitcoin is like the same as gold. It mined to have it and to grow your bitcoin. No one could never know who can supply the bitcoin. It is very confidential to know. It so wonderful that we have special tools to mine like the ordinary miners. Technology life goes through a good and better life.
