I think say you really dy my mind here, na mostly ignorance they drive ponzi scheme forward, but make we know say no be only uninformation, misinformation na another thing wey dy drive am forward because most of this people wey they still invest in ponzi scheme think say na him be the real one depending on wetin them hear.
Then as for the aspect of greed, na that one nai dy pain me pass all, because some people know say na ponzi scheme, but base one say them wan turn millionaire overnight, them go still risk their money thinking to hit and run, most times their money go just hang in the process, then go start to dy complain say hard I know, so this three things wey be misinformation, uninformation or greed na them dy mostly make people to venture into ponzi scheme instead of Bitcoin.
