Just saw Erbao mention that the term 'Bitcoin' was coined by Yang Linke, which reminded me of this businessman from Wenzhou. I have two deepest impressions of him: 1. In 2017, he launched AICoin (ICO) and hyped it as a hundredfold return. After the 9/4 crackdown, it was liquidated at the cost price of 0.9 yuan (most people’s cost was 6–10 yuan), leaving those who bought at the peak bleeding money. 2. He manipulated Bitcoin Diamond (BCD, a fork coin), hyping it as Bitcoin 2.0. After pumping and dumping, it completely went to zero. My first article on my public account was criticizing Yang Linke’s BCD. I still remember that article broke 10,000 views, and it was from that post that I started my journey of writing for my public account.
