In my personal experience, I first heard of it 1 year ago in a online forum game, people sold gold for Bitcoins, around March, gave it no importance at first. Now im kinda utterly commited to it. Really an interest subject of study.
I heard it from my high school students, and i kind a felt like they were just kidding around and soon i observed one of my male students seem to be different since he has this curly hair and i was shocked cause he has this straight hair already hahaha! And additional to that, he already bought his new laptop...and those are products of his perseverance here in bitcoin. So of course i got curious about this since i need extra income for my family. In short, i owe my students some plus scores in their next quiz hahaXd #HappyLang!
