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.
