Only Bitcoin and Gold

Trading is something where losing is always easier than winning. Many people take a small profit and run, but when they are caught in a loss, they tend to hold on for the long term - refusing to sell until it goes back up, which is a very bad habit. This is also what Buffett refers to as 'picking up pennies in front of a steamroller.' Each time, it seems like they are making a little profit, appearing to have a high success rate, continuously winning, but as soon as they encounter a total loss, they end up giving back all their profits and even incur further losses - this essentially is a strategy that only focuses on short-term emotional evaluations while ignoring systemic risks.

So what is a better trading strategy? Only buy those assets that can withstand floating losses in the long run and truly have the potential to recover. Only then can it be equivalent to floating profits - that is, over the long term, they have gone through many cycles, but the peak of each cycle is higher than the peak of the previous cycle, a fact that history repeatedly proves. As long as your assets consist solely of such combinations, you possess significant risk resistance and investment advantages, meaning you do not need to judge the timing of entry because each moment is a good opportunity for the future.

Historically, the only assets worth long-term investment are a few, such as the US stock index, gold, and Bitcoin, among others!
