No, it is u that dont get it. U ARE COMPETING with asics because asics will push difficulty to the coins u are mining. Profit margins for mining are thin these days. It is abit higher right now compared to 1-2 months ago due to recent price spike but that will correct soon as more hashrate enters market. U can always have an alt coin to mine but it is gonna make low or negative returns for u because of difficulty increase, which are pushed by asics from other coins.
If GPU miners are pushed from ETH to another coin that is FPGA-mineable then:
1) diff goes up but an FPGA is still more profitable than a GPU;
2) diff goes way up, a GPU is not profitable anymore, still profitable for an FPGA;
There are many other variables in this and many other reasons why this might or might not work, but what you're saying doesn't really make much sense. I think you're misunderstanding how difficulty adjustment works. It will go down if profitability turns negative.
No because u can buy an FPGA, so can everyone else. FPGA is the new GPU. It just costs money which everyone has. Mining is easy, everyone can do it.
U make such an FPGA first. U are first and it has 6 months break even. Really quickly, everyone else will have an FPGA and break even will go to 11-15 months or so, the rough average.
See post 268 for a simpler illustration. I leave that as the last explanation of the conceptual flaw.
How fast can u start buying the items and do this. Lets see this go forward yes.
