It's a classic scam that has existed long before crypto. I guess it works because all scams have been tried before and the scammers stop doing the ones that don't work. That is why we all get so much spam in our email...because people out there actually click on it. Who? I met one once...I was like don't click on that! People are dumb sometimes. But that doesn't mean it's your fault if you get scammed...it's the scammer's fault. But like someone said, it plays on your greed.
