There are still many who fall for these kinds of scams, it really comes down to a lack of knowledge. As they say, it's just easy money or HYIP. Even though regulations are getting tighter, some still manage to slip through, and most of these scams happen in poor countries.
Lack of proper orientation is what contribute to these kind of scams and it has nothing to do with poor countries or big countries. Scam can come in any form and people that are not inform about the information can be a victim. Even people that has money invested in crypto becomes victim from this kind of scam but there own is packaged in the way they wouldn't suspect and once they click on links, they lose everything and their wallet becomes drain in a matter of second.
I urge us to invest in knowledge as we are investing in crypto because there is no ignorance excuse in crypto. Even the people that are carrying out scams in crypto invested on their knowledge and then repackage it in a way to lure victims do their bid and once they set trap for you and you successfully accepted it, then be ready to fall for them and lose everything you have on your possession even if you might not have anything to invest in crypto for that time.
