View my earnings and investment portfolio details. Follow me to learn investment skills; trading strategies are key to gaining profits and controlling risks. Trend-following strategies can profit in a one-sided market but may backfire in a volatile market; mean-reversion strategies operate in the opposite direction when prices deviate from the mean, suitable for ranging markets but struggle with trend changes; arbitrage strategies capture price differences for low-risk returns, but opportunities may be scarce. Investors need to reasonably match and flexibly adjust strategies based on risk preference, market environment, and other factors.
