OP obviously a GPU miner and maybe butt hurt after he spent $300 on a 7000 series GPU outputting 300mhash, and now people are able to buy USB miners 3rd of the price to compete against those last few GPU miners that are still in the game.
my suggestion is dont spend $300 on a GPU. buy 3xUSB miners. atleast your hash rate per dollar will be higher, and electricity bill will be lower.
or rent hash power from an ASIC miner if you cant afford to buy one in full
$300 7xxx series would get you around 660hash. more power consumption, but currently. 36% more profitable then bitcoin.
usb miners are a at a more fair price @ 1btc. but still not worth it
lol @ people who bought it at 2btc.
edit: you assume only 10% increase for an entire 30days? buddy, the last 2 cycles were 2x% @ 11days and that's just the tip of the dick when avalon ships their chips and other production starts ramping up.
