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 disagree with the rule that says never be greedy as a trader. If you are not greedy in crypto trading you will be making peanut, you will sell once you have 5-10% profit. But if you are greedy you will make 1000% -5000% profit
