The prerequisite for sustained and stable earning is that the target itself follows a regular pattern. What does' regular 'mean? Respect price structure, signals, and moving averages, with logic for declines and expectations for increases. On the contrary, coins like those that have a wave of flow, frequent insertion, and irregular moving averages also make money by luck. Taking ENA as an example, it is currently one of the few "reasonable coins" in altcoins, with a clear 4-hour moving average long position and appropriate volatility. Even if you missed the last oversold rebound, this coin is still worth paying attention to.
