I heard it on google while I was looking to earn some extra money and then my friend gave me a brief idea about bitcoin and the earnings that we can make from it.
Good thing to know that you found bitcoin out by just searching it around google and I think you didn't understand it that's why you need a friend to discuss it to you. Same experience as mine too. And luckily, both of us are in good signature campaigns.
difficult to be interested if you know bitcoin from google. but most of those who are interested in bitcoin on the advice of friends. including myself, I was told by my friend about this remarkable bitcoin.
