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 agree that we should never be greedy when we are trading becuse it will result a loss for us, before i am so greedy because i have lot of bounty tokens and then the value of it pump really high and i dont sell it immediately i still keep it because i think it will incressed more but i am wrong the value of my bounty token was dump and i loss a huge amount of money by being greedy.
