Saying you want to quit an industry is a stupid idea, especially for investors (speculators).
Capital is fluid, and industries rotate. The consequences of constantly quitting this and that might be:
When the crypto market is booming, you see your stocks stagnating for years and impulsively sell your US stocks;
When the US stock market is booming, you see your A-shares constantly falling and vow never to touch them again;
When the A-share market is booming, you see the stagnant crypto market and decide to quit;
When BTC skyrockets, you decide never to invest in gold, which has been stagnant for ten years.
My brother, why are you always the one who gets hurt?
