You can make money by speculating in cryptocurrencies, which is a side job. No one can get rich without windfalls, but you can't make this kind of money for a long time. You can't mistake the result of coincidences as your own ability. I'm afraid that I will develop the habit of making this kind of money, but I will never have the ability to make this kind of accidental income, just like Liang Xi made 10 million by shorting on 519, but ended up with nothing. Now he is in debt of tens of millions and only has the memory of his luck.
