The first time I heard about Bitcoin was because of all those Ponzi schemes and hype on social media. People close to me had also heard about Bitcoin, but we didn't pay much attention to Bitcoin time. Later, I heard that Bitcoin can make money, so I started to study it slowly.
The first time I heard about Bitcoin was from the TV news, telling people to stay away from pyramid schemes and virtual currencies. Big gains are often scams. Later, the friends around me gradually deepened my understanding of Bitcoin. They often talk about mining, but I still couldnt understand it at first. I laughed at my friends and stopped dreaming. When did you start mining coal? It turned out to be a large computer.
