I think pyramid scemes will exist forever as people are always wanting to earn money fast. Unfortunately, they usually even know they are investing in a pyramid, but they still have hopes they will be able to earn money before the total scam.
sadtruth, as long as there is demand, there is supply too. greedy is human nature, that's why they want to earn fast money
they often dont use their logic as well before doing something, at that time, the greedy works
it doesnt only happen with newbie, but the experts also can do
I myself try hard to use my logic before investing to avoid this one
