Anyway GPU Mining is DEAD, with actual diff and price of 91 USD it's not profitable to GPU mining anymore
Ok then stop mining. Simple solution. Bitcoin needs miners to protect the network. It doesn't necessarily need you (or me, or any individual miner) to mine with your specific inferior hardware.
Mining isn't a "free money for nothing" game. It has a purpose. That sole purpose is to protect the network. Higher difficulty means more protection for the network. Coins only have value because people believe the transactions are irreversible. Lower difficulty enough so that someone can easily attack the network and it doesn't matter how many coins you have because they will be worthless (x BTC * 0 = 0).
Yeah! thats why is illogic "Ban" chinese people.
You can't forbid anyone to mine because of the nature of bitcoin. you can or cannot mine for profit, but that people who does (like ASICMINER) shouldn't be ban to mine.
Maybe I, or you, don't have powerful hardware. That's why we search other investments. In ASIC ways or Shares of some type.
Anyone can use bitcoins and you can't exclude anyone.
