Sometimes it is not actually greed rather it is misconception or misinformation, there are people that don't know the right coin to invest in that is why you see some persons investing in shitcoins thinking it is Bitcoin but they are still to be blame because they don't have to assume or conclude on what they are not sure of and some people because of what someone told them, they will follow suit without confirming the information first before taking action, that is a very wrong thing to do as someone that wants to learn and be successful in Bitcoin investment.
It would be very strange if someone thought that shitcoin was Bitcoin because no matter how stupid a beginner who wants to become an investor in Bitcoin, they can still ask whether it is Bitcoin or not because Bitcoin only has one name without any other name as a disguise and even if there is, there must be an additional name in front of it. So it's strange if beginners who receive information from other people immediately swallow it raw without investigating it further and they are silent without asking whether it is true or not.
In fact, everyone who receives new information, whether it is about investment or other things, will definitely ask questions to have a clearer source for what they hear. Because those who do not ask further questions on every new information they receive, in the end they will also go astray on the wrong path which may be caused by making a mistake in determining their own choices. So asking is a very mandatory thing even in sectors that are already running on the right track, because it also functions to ensure whether it is really good or not.
