Honestly, material things have been enough for a long time. A family of three spends less than 100 yuan a day on daily expenses, and luxury goods only amount to about 100,000 yuan a year at most. Desires are naturally low.

But I just can't quit trading cryptocurrencies. The joy of earning 500U and the pain of losing 50U—these psychological fluctuations are more stimulating than anything else. Making a small profit makes me incredibly happy, and losing a small amount of money still makes me feel distressed for a long time—this is true addiction.

To put it bluntly, the psychological pleasure and excitement brought by trading are indeed more addictive than many other things. Every market fluctuation is a new expectation, every trade triggers dopamine. This addiction runs much deeper than simple material consumption.

What exactly makes traders so obsessed? Maybe it's this instant feedback—though the amount is small, the impact of wins and losses is real-time, tangible, and impossible to ignore.
