Regarding the Ponzi schemes part, i agree 100%, but i guess it's just natural selection, the ones that are dumb enough to actually invest in stuff they don't know end up losing... For example, i don't intend to be greedy, i only invest in coins that are already established, yes, it will be less profit in the end, but at least i don't have the risk of it being a scam... For example, i don't feel any anger towards the guys behind bitconnect, they were greedy but they were also smart, i'm more angry at the ppl that actually invested in it, everyone said it was a scam and people still invested in it...

I don't know if it is because of the way i was raised but i'm a greedy guy, i don't want to live an abundant life, i always want more! The generous part it really depends, i'm generous for some stuff and not so generous about other stuff. I'm generous to my close friends, but not so generous to strangers...
