I was wondering how'd you discover or know about bitcoin? Did someone refer you? Did someone show you what you did? Through the news? Share something here. 
I'm not totally familar in bitcoin last few days but today I'm so exciting in bitcoin. My classmate earn btc using an internet and I want too. So I ask my classmate how to do that, when he show to me I'm convincing to do that with spending too much time to earn btc.
