If your talking about bitcoin, the most and effective way to profit is dont look on price daily. Simple right. The more we monitored the charts and its flactuaions we will be attempt to sold and panic when we its down the same way when its up. Temptation and impatience is the most common reason we tend to sell our coins even we know that the price still increasing and can be doubled in for the next month. Because in bitcoin its better not to use your eyes but use your mind and heart to trust bitcoin.
