If 24-hour trading does indeed amplify volatility, the reason why the cryptocurrency market is more volatile than the stock market is because the cryptocurrency market trades 168 hours a week, while the US stock market only trades for more than 30 hours in a week, and Big A trades for more than 20 hours a week. The cryptocurrency market has 5 to 6 times more trading time than the stock market, which is equivalent to one week of trading in the cryptocurrency market and five to six weeks of real-time trading in the stock market. Nowadays, the trading hours in the stock market are still the continuation of the trading mode of on exchange counters before the popularization of electronic technology. With the development of computers and network systems, 24-hour trading is probably the trend. Increasing volatility does indeed increase difficulty, but it may be a blessing for traders as greater volatility increases opportunities. But it will also force medium - and long-term investors to focus more on factors such as mid value fundamentals and growth certainty, so that they can hold the target and sleep soundly.
