I spent six months focusing on the relationship between US stock market policy news and leading stocks, and I've begun to understand the logic behind these leading stocks and the continued bull market. My first move into US stocks was to buy Tesla, and my first move into Hong Kong stocks was to buy Alibaba. Looking back, this was a wise move. Choosing a leading stock in a sector and embracing it can at least minimize losses. Hold first, learn later, and then gradually release funds to explore deeper areas. The same goes for cryptocurrency trading. For newcomers, embrace BTC and the leading stocks first. Once you've mastered BTC, then explore the altcoin market.
