A lot of people make the same mistake by being too greedy, and ignoring the small profits and not using the proven recipe for success in Bitcoin by buying low and selling high.
They're not been greedy instead acting smart. Day trading or trading in general isn't an activity everyone's can partake in. Sometimes it can favor you although majority of the time it won't. Investing is quite different from trading, if you're trying to encourage forum members into trading for profit then you first have to emphasize on the importance of acquired the required knowledge and skills needed to profit from trading.
It's quite tempting to try to profit from the small gains whenever you see them but if you inquire from those who have been in the industry for quite a long period of time, they'll review "Ignoring the small profit" is quite the best decisions you can ever take as history has always proven, "hodlers profit the most with less stress".
