If you analyze how people learn from their mistakes, a lot falls into place. Most of the time, they just don't learn. As an example, I even recently watched a video on the channel of the Amarkets broker about the safety of my finances on the network. But despite the fairly well-described information, people still often make mistakes and lose money.
You'll be surprised, if to analyse which were scams tens years ago, hundreds years ago and thousands years ago we'll see that nothing mainly changed: people are being scammed with the same patterns. The little difference is just in some technological decisions: to steal golden coins, paper money or digital money. Because new generations learn the same each time. So we need to teach basics every time to protect others.
The funny thing is, most people who get scammed, are people who tried to scam others. In my nation there is a story of a scammer who says that they tricked people with gold, and sold it very undervalued, but turns out it was fake gold, and he defended himself saying "those people tried to scam me by buying it cheaper than it worths, I just merely scammed them back" and that is a great story.
In crypto there are stories about people getting insanely rich with some lucky moves, and naive people who hear this thinks they could find something like that as well, in return they end up losing money all over again. Thats what I believe is the main reason why it is so rampant here.
