Make a wiser choice with the situation, controlling greed might make you safer when cashing it at that time, but if the decision chosen is to keep holding it then at least you have to be more consistent so as not to be affected by the current market situation weakened.
When a traders thinks of cashing out, I see that as a good thing as that doesn't show some greed.
Cash out when it's time, and when a trader already makes some profit, that's the time to cash out, big or small, it matters because profit is a profit.
