#Bitcoin  is so decentralized that it’s hard to tell how many people even use the network…no central authority = better privacy and security.

Best estimates are usually around 200 million, but we can’t be certain.

Just think about it, technology hasn’t progressed enough to be able to tell how many people use #BTC  and it’s had almost a decade and a half. There’s a good chance we will never be able to tell. Satoshi’s genius is mind boggling.
