Here's a phenomenon that really hits home—if you meet someone with a decent salary, but they wear affordable clothes, live in an average place, eat casually, don't go shopping, rarely travel, and have no hobbies like smoking, drinking, or tea, and their daily expenses are basically zero. Don't think too much; nine out of ten times, they're either trading stocks or messing around in the crypto world. The common trait among these people is—they always want to invest their money, even if the idle funds are minimal, they still want to play. They cut living expenses as much as possible just to free up principal for trading. This is especially true in virtual assets; once they get involved, their desire to spend drops sharply, and all they care about are market trends.
