I know of at least 100 rigs out there that would jump to a dev fee miner if it was comparable to the amd miners. A little development and it'd go further. There are a lot of us that have nvidia. There's a lot of money in the smaller altcoins when they pop up, and the versatility of the 1070s is why i chose them over the 480. I dont care about initial cost. Anyway, if someone wants to start developing one, there are people that could fund a dev fee % miner.
