Wait, get back here, for I got here late for the party. I, too, have a scam in mind that would easily net ten grand per shot, and I'll sell it to you for only five grand, and if it doesn't work as outlined, then I'll double your money back.
The beauty of my scam is that it involves nothing technical, for only a bitcoin (even any alt would work) wallet address is needed. I'll give you a hint: It involves a service for hire, one that's not delivered after payment is paid, and the person paying for said service would be a foul to turn you in even if they knew who you are, which they wouldn't. Hint number two: A many persons going through a divorce may consider such a service, same true for somebody close to somebody who was done wrong by some other. No more hints, for I'm calling it a night because I'm dead tired.
A hitman for hire through Bitcoin? Only the very gullible would fall for such a thing, but then again the reason you get some many scam emails from Nigeria is that once in a million people there are some very gullible.
The very gullible, and the very desperate. A fake hitman (which actually was an undercover agent) was part of the reason why Silk Road's funder was arrested.
