Well I think that in terms of earning and profit, I feel that you need to be not greedy because most of greedy trader and hodlers turns out to lost funds instead of gain and earn profit. Just keep in mind that profit will always be profit no matter how small or big it is.
True, greed will not end with a profit even many have regretted it because those who are greedy always get lucky in the end, so trade wisely and always take profit even though it seems small and not too big.I agree that greedy is not good
