I've been trading in the A-share market for 8 years, growing my capital from 300,000 to 3 million. With this experience and confidence, I recently opened a U.S. stock account to explore trading methods here.

Recently, I've been trading options and have gained some insights, turning 25,000 into 50,000. Here are my thoughts:

First, always identify the trend—either bullish or bearish. Picking the right direction is crucial. Given the current long-term bull market in U.S. stocks, going long is generally more favorable.

Second, be bold and buy at lows. Don’t fear further declines—hesitation means missing opportunities. Big rewards require big courage.

Third, based on your risk tolerance, take profits decisively when your target is hit. If you’re like me and go all-in, aim for ~50% gains and cut losses at ~20%. If you diversify, consider taking profits after doubling your position and cutting losses at 50%.

Here are some beginner-friendly call options: First, the Nasdaq 100, $Invesco Nasdaq 100 ETF(QQQM.US), is the easiest and works in any market. For big market swings, go for $Direxion Semicon Bull 3X(SOXL.US)—huge upside potential. If you expect low volatility, long the strongest "Magnificent Seven" stock or short the weakest intraday for better returns, like $NVIDIA(NVDA.US) or $Tesla(TSLA.US).
