The big empty wing of the poker boss in the currency circle.

Da Kongyi, whose real name is Du Yitian, was born in the 1990s. It is said on the Internet that he is only in his early 30s. Because I liked playing football since I was a child, I was named after the football player Oku Tsubasa on the Internet. Because I bought IOTA coins with 100,000 yuan of stud, my net worth rose to 3.6 billion at the highest level in 3 years, and I became a god in one battle. I am called the king of stud, no one else! He is also one of the legendary figures in the Shenzhen currency circle.

In 2013, Bitcoin was in its bull market. At that time, Da Kongyi, who was studying in the UK as a sophomore, came into contact with Bitcoin. During the summer vacation, when he returned to China from the UK, he wanted to try mining. He spent 20,000 yuan on Taobao to assemble a GPU mining machine. In fact, GPU mining machines were no longer the mainstream mining machines for mining Bitcoin at that time. The mainstream mining machines at that time were ASIC (highly customized integrated circuit chip) mining machines represented by the Avalon mining machine and the Roasted Cat mining machine. So he found another way to mine some altcoins that few people would mine, such as World Coin, Feather Coin, etc. After that summer vacation, he exchanged the altcoins he mined for 80 Bitcoins. At that time, the price of one Bitcoin was about 4,000 yuan, which can be said to be the first pot of gold he earned in the currency circle. The bull market in 2013 allowed Da Kongyi to enjoy the joy of "making money while lying down". During that bull market, his market value reached its highest value of 1 million yuan. For a young man in his early 20s who has no background and is not a second-generation rich man, 1 million is a huge fortune. However, he was not immune to the bear market that followed in 2014. His net worth also dropped from a high of 1 million to a low of only 100,000 yuan. During that time, he was very depressed. "I just don't feel satisfied. I slapped my thigh every day, thinking that it would be better if I sold it earlier."

IOTA’s battle to become a god happened in the second half of 2015. At that time, not long after the bear market in the currency circle ended, the prices of many virtual currencies had been fluctuating at the bottom. At this time, a coin called IOTA opened for crowdfunding. The crowdfunding price of IOTA was about 0.001 yuan. Da Kongyi took the 100,000 yuan he earned in the currency circle and bought it all. At that time, there were not many people in China participating in crowdfunding for this project. It is said that only 7 or 8 people in the country participated. But in the end, there were only two people who held it but never sold it. One was Da Kongyi, and the other was Jimmy, the head of the IOTA Chinese community.IOTA raised a total of more than 1,300 BTC at that time, worth about 3 million yuan. This is where the legendary road of Okora Tsubasa begins. For a year and a half from the end of 2015 to June 2017, the price of IOTA has been quite cheap. Even in the bull market in the currency circle in the first half of 2017, its growth rate was not very attractive compared with many currencies that had the highest growth rate. But since the ICO craze started in June 2017, IOTA finally exploded. By December 2017, it once rose to about 36 yuan, which was nearly 36,000 times higher than the original crowdfunding price. Dakongyi originally invested 100,000 yuan, and its market value was nearly 3.6 billion at its highest.
