> I agree that etherium is not a classic pyramid scheme, but for me it fits many criteria so I feel like it's a fair simple description accessible to anyone

> I don't think etherium is necessarily a bad investment if you have no moral or are not well informed

Is it immoral to invest in Ethereum if you truly believe in the promise of the technology? Are you saying that anyone who believes in the promise of the technology is ill informed?
