Let me talk about myself and my classmate first. He was born in 1990 and entered the cryptocurrency circle in 2013. He really started to have fun in 2016. In 2017, he caught up with the bull market and made his first 10 million with a capital of 10,000 yuan at the beginning. After that, he became arrogant. After losing all the money he made overnight, he also lost all the savings of more than 3 million yuan of his parents' hard-earned money. He also borrowed 5 million yuan from relatives and friends to speculate, and paid all his tuition fees in the market. In total, he lost more than 8 million yuan, and the remaining coins were used to make thousands of times the money in the bull market.
