Also one can make the following observation:
There was only 1 GPU chip manufacturer who dominated mining farms: AMD.
Today there are 2 FPGA chip manufacturers who are at the basis of all FPGA farms: Altera (in the BFL Single), and Xilinx (Spartan6-LX150 in all others).
And soon there will be 3 vendors of ASIC mining chips: BFL, Tom's, and nghzang's companies.
So we are actually becoming more decentralized over time.
Nicely put mrb.
Also, what do you guys think it helps becoming more and more decentralized?
A. Buy a small $150 device that you can just "plug and play" via its one and only USB cable
B. Buy video cards that you need to put inside your computer, check if you have free slots, upgrade MB if not, create racks as wooden scaffolds, have a lot of noise and heat, etc.
