Crypto is a perfect engine for scammers because it's still unregulated and it's also the wild west when it comes to making money quick with less efforts. .
I say NOT really a perfect engine for scammers but we can't deny that it was one tool for them to fool people and take advantage of the situation as they can be anonymous. Yet, many scammers have been captured and put in jail while using cryptocurrencies and it was because of the participation of the community.
I see that people are not learning how these scammers do, yet some people still fall into their hands because of their greed. Generally, they are now cautious with their actions and decisions when it comes to choosing coins to invest with.
People are acting as if scammers do not exist in the fiat world and that is the thing that bothers me the most. I mean fiat world has a lot more scammers and it happens every single day, so much so that there are companies out there who scam people constantly. This means that crypto of course has scammers, because everywhere and every currency has scammers, even non currency related stuff could be used for scamming as well, like scamming for influence or power as well.
All in all, you are not going to stop people from lying to get more. That is the nature of humanity and it will continue to do so until end of times. I am guessing that the best thing we could do right now would be just focusing on ourselves and how to prevent getting scammed.
