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.
If you are a good and active trader then it is too much important to study and watch the price on regular bases. In fact it is to much important to watch the price of bitcoin regularly specially if you are holding bitcoin for short time, so that you can take a right decision in a right time. To me i personally studying the market of bitcoin from time to time using preev.com.
