No crypto currency that I know of has succeeded based on the utility of their proof of work algorithm producing something useful. Only proof of work algorithms in service of the currency itself have made an impact.
I'm thinking more that a blockchain enthusiast will design a new coin that abuses the raytracing hardware into running some new crypto-token just because.
This series tentatively looks like it won't be subject to the insane price hikes and scarcity of the 10 series because it's already expensive for adding more diverse hardware that doesn't immediately help you mine ethereum (or whatever's the GPU coin of choice these days). But you never know...
It doesn't need to _do_ anything as long as you can convince people that they should buy RayCoins because everyone else is going to buy RayCoins and they'd better get in on the ground floor here.
