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!
Bitcoin is produced through mining. I think you should learn first about bitcoin before you plunge into this world. Bitcoin total supply is 21 million. Now earning via faucet is very low payment. If you have enough cash you can buy bitcoin via exchanger. If not, just be active in bitcointalk you will learn a lot from this forum.
