I mean, I literally had someone threaten to sue me for the 100 bitcoins that I supposedly owed them for their week of mining at like 50 Gh a couple of months ago. Seriously. He was basing his numbers on some outdated profit calculator that some eBay seller linked to that used a difficulty from pre-ASIC days, probably to screw someone that didn't know better (successfully). It was sad, funny, and highly annoying.
Wow, it's unbelievable what some people think. He probably paid < $100 on eBay for a 50 GH/s miner and expecting to rake in $5000 / day of internet magic money.
Ok, so someone mislead him...but seriously, maybe he should have asked the seller why on earth he would ever part with such a magnificent device.
This guy is going to get raped by every ponzi scheme out there.
