Making money in a bull market is easy; everything you buy goes up.
Actually, that's not true.
You need to know what time and where to enter the market, as well as when to chase gains, because effectively using your allocated funds is important to avoid opportunity costs and capital costs.
You need to know where the sectors will rotate to.
Even when everyone else is making a profit of hundreds of thousands or even millions, you still need to control your greed and avoid excessive leverage.
You need to know when it will stop "going up continuously."
You need to control your emotions more than ever, and be more perceptive than ever, because things are developing quickly.
You need to accurately grasp when to be greedy and when to be fearful more than ever, because this is crucial in the relatively short time frame.
Simple conditions are not simple. The reason it is said that "making money is easy" is to remind you that it should be easy.
However, in the market, the only thing that makes making money difficult is your own thoughts.
