To learn there is always a sense) And the experience that comes after the loss of money, should lead to the fact that in the future this will not happen again. But there are some participants who even after losing money continue to participate in Ponzi schemes, hoping that this time they will be able to get out of this Scam in time and they will be able to get a profit.
At some point a lot of people tend to join this pyramiding scheme, first, they just don't know it is really a scam investment or not, 2nd is I think they want to become part of the scam to earn a profit.
When you already know how it works you could easily identify scams or pyramiding projects. And at some point, you could actually ear in this investment that is why a lot of people are encouraged to join because they see other people earning in it. Affiliate or referral is actually a big part of it since you could earn when you invite someone that also invested in the program.
