One of the people who was invested in this was a medical doctor, so I doubt if greed makes any distinction based on IQ.
It's important to understand that being a doctor has zero meaning when it comes to actions outside your comfort zone. Your doctor (medical) IQ might be sky high, but your IQ in other fields can be incredibly low, especially when it comes to investments and risk/reward ratios.
Greed is destructive, and it shows time on time again. If you can't prevent yourself from taking extreme risks, which these ponzi schemes are, then something is actually wrong with you. Investing in ponzi schemes, and especially when it is this obvious, is only a matter of you having a low IQ, at least in the investment field.
Nope. It only exposes how retarded people are. Bitcoin keeps growing as always. If we go by your logic, we wouldn't be where we are today.
Do you want to tell me that Ponzi schemes are good for Bitcoin? I have spoken to several people who got burnt by scam ICOs and Bitcoin Ponzi schemes and the majority of them does not want anything to do with Bitcoin after they lost their money on these scams. These people are from all walks of life and they always blame the technology and not themselves.
They even take it a step further, by warning people against "Bitcoin" investment. This has a much wider impact than simply one individual that got burnt, because every person that this individual come in contact with are poisoned by his or her anger and resentment towards this technology. <not the scammers/criminals that used the technology>
You do not grow adoption by exposing people to scams and Ponzi schemes, where they lose money! ^hmmmmmm^
