Scammers are using social media to promote such scams. And since there are all kinds of people on social media, there are a large number of people who are inexperienced about crypto. And usually these websites target them to scam. If you take a closer look at Facebook, you will see how they are promoting through advertisements of such fake websites on Facebook. People who are inexperienced about crypto should be more careful before believing anything, because there are many scam websites online now in the name of various popular projects.
I just had to LOL at the repetitive nature of this post. I think if you kept writing you would have gone on to mention that there are many scam sites and inexperience people falling for those scams.
About this particular scam, I'm a bit puzzled. I'm not all that familiar with Tron but didn't think it was one of those coins you could mine. It's strictly proof-of-stake, am I right? And if that's the case, then anyone offering Tron mining services is by definition a scammer. Even if that isn't true, those promised returns are higher than what anyone could earn by staking it or even mining a typical altcoin. Too good to be true means
not true, always.
ScamViruS is correct, though. The idiots behind this blatant scam are clearly targeting individuals who don't know much about crypto but might have heard about the outrageous profits some people are making and want to get in the game. I'm sure there are tons of people like that around, especially with bitcoin being above $50k.
