Well, all these things are not new. They're practically problems that keeps happening, not just in the crypto space, but in every other area that involves finance. Let's not forget that not all Ponzi schemes are crypto related... Some are literally based on fiats and we often see them from time to time.
And, I'm not exactly sure of how people think that they can get rich with $100. If someone plans on getting rich with such amount, then whose money are they getting rich off?. There are certain offers that practically sound like theft because they're too good to be true, but people just don't care for certain reasons known to them. Getting rich has nothing to do with luck or messing around with unrealistic offers. The world doesn't dish out wealth on a platter of gold.
