Unfortunately, greed and lack of proper research make many people easy targets for scheme like this. Most Ponzi schemes don’t attract investors by offering realistic returns, because the way they attract them is by promising quick and huge profits. For real what surprises me is that many people are willing to hand over huge amounts of money to strangers but won’t spend a few hours learning about bitcoin or how investments actually work. Cases like this is a reminder that if an investment opportunity sounds too good to be true you should do proper findings and not fall victim. Education remains one of the best defenses against fraud
Educated people get scam though Ponzi scheme too, scammers are very smart people and only dull people will fall for them, regardless of your educational status, if you're educated and you have a bad habit of making money by quick end then you will be scam easily, scammers also project unrealistic amount to win if you invest lesser amount, greedy people who can't take time to review will jump into it for quick money only to be scam.
Education can't save you if you're a greedy fellow, you will always fall for Ponzi scheme scam, it takes a brave scholar to escape scammers, as a scholar with integrity you will always research before investing and when you're not convinced you let go. Many people are not patient enough to hold Bitcoin for long they all wanted to be rich overnight which is not possible.
