That's right, but we are not always greedy. We need to understand where the greed is. It is essential to make you rich. If many people are not greedy when the bitcoin increases from $ 1 to $ 300, many people do not become rich. All is the opportunity and the moment, choose the right time to greed.
Greed is the thing that makes you quest for more and more and this quality if human can be instrumental in the accumulation of wealth in the crypto business and that is something almost all of us here wants. The impact of this trait and practice is important to be observed for it may at times carry you away from your altruism and this is bad.
If you are able to keep equilibrium between the two, better stay hungry and give it your best shots. Look at Tim Draper! Is he greedy for he is still holding his Bitcoin even if the value has surpassed a billion dollar.
