Trading is actually a behavior with gambling characteristics, similar to gambling. The two should not be generalized together; for example, guessing high or low, where there is only win or lose, is gambling. Although trading also involves two directions of price movement—up or down—it is not considered gambling. For instance, if a certain coin is currently priced at 20 USDT, and the expectation is to rise to 30 or fall to 10, the trend could be to first rise to 30 and then fall to 10, or to first fall to 10 and then rise to 30. This is a form of certainty. Looking back at history, the previous cycle where Ethereum dropped from 5000 to 800, then rose back above 5000, and now has fallen again, the difference from gambling is that it can go either way. Gambling has only one outcome, but candlestick charts can reflect both. The only variable is the trader themselves—what kind of time, environment, state, and situation they are in when making a move. The account's profit and loss fluctuations can be based on 10 or 30, and position management becomes especially important at this point.
