Zhao Dong should do whatever he wants to do, whether he is starting a business or working, but he should not play with leverage or short-term trading. At the peak of 2017, he had more than 2 billion Bitcoins in his hands. Half of them were from friends. Not to mention the dividends given to him by his friends, his own half was also more than 1 billion. Only after being fooled did he know the pain. The reason why Zhao Dong is poor is that he is too hardworking!
