I am trying to learn and share with u guys about bitcoin. I think it is gonna help someone like me.

"Research produced by the University of Cambridge estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin"

one more interesting knowledge is :
"The word bitcoin first occurred and was defined in the white paper that was published on 31 October 2008. It is a compound of the words bit and coin".
( The white paper frequently uses the shorter coin).

so guys you can also share good and short info about bitcoin.
