Well ultimately its up to you, but I would mine FTC right now, I believe its about to shoot up in value, its at a all time low right now
on my one 7970 i get about 587 kh/s - 600 kh/s. So im wondering if this would be a good idea? :? Im mining Xencoin right now (solo) for the fun of it. I've found 2 blocks.
After mining Xencoin make sure to come to PXC the coin of future in my opinion. The developers are really active and there are lots of project on standby to be released soon. so get in quick. Right now I am mining Xencoin as well for fun.
