Crypto world is plenty of scammers, wich does offer you something very cheap or new, the thing is crypto did atracted a lot bad people wich were into fiat scam projects, now they are more safe at crypto world. There is no a valid concept why they scam, besides the easy money maker, those people usually looking for fast and easy money, and newbies usually fall in the traps, i believe they scam because the opportunity shows up to them and blind people invest and believe its possible to earn money without work.
Well I think majority of youth they are jobless and they have nothing to do so they are confused what to do in this kind of situation they engage themselves in some bad things and the scam people take advantage from them so I think if government provide them a good job so Im sure society will be free from these kind of scam.
