lol its all noobies that are being introduced to mining. Some People I know buy them for fun, though just 1-2 for entertainment
entertainment purposes = wow, look every month i'm loosing money to energy cost and I overpaid for the amount of coins I am getting? wtf
Not everyone pays for power though. Who knows, maybe they just like getting stoned to trip out on the flashing light, LOL!
Nothing wrong with people willing to overspend on outdated mining hardware, it helps to keep the ROI possible.
