A friend of mine has been playing with cryptocurrency for 5 years and is now financially independent. The cryptocurrency circle is a high-risk speculative market. He has been liquidated many times, but he has survived every time. He has delivered takeout, driven for Didi, and moved bricks on construction sites. It was very hard, but he never gave up. He currently has two large flats in Shanghai, a Lamborghini, a Cullinan, and a girlfriend in her 60s.
