What is there with ground floor opportunity?
nothing really... unless you have a ton of i7's sitting around not dedicated to anything else.
the problem is that any coin that is technically minable with CPU (like XMR or ETN)... there are by comparison SO many high end GPU's already mining it, it literally would get you pennies a week. 1-2 years ago you could have done ok, but frankly, it's not worth it at this point. There are millions of GPUs cranking on every algo out there, any 1 or few CPUs is not going to amount to anything. If you just want to do it for fun, maybe try ETN or SUMO, but you really must get into GPU mining id you want to make any $ at all.
