While trading we have to follow few rules and without following those rules there is no way to be a successful one except a successful by chance. There are lots of rules of them greedy plays a vital role. While trading never be greedy. If you become greedy while trading then you can be assured that there is 90% possibility to be a lessor.
I also agree for this.but in real trades,greedy is good if sometimes you do aggressiveness to make profit in fasties way.then stop it again to be greedy.it depends on the flow of coins or anything that can push in that coins.you can follow the flow of you're coins that you trades.that's my thinking and I use it already before.
