I been looking into it.
Being that Bitcoins are getting harder to mine. But even though its listed above >$3.xx Nobody is accepting them as cash currency as-to bitcoin.
I couldn't find a legit provider that trade Litecoin for cash.
So its a risk im guessing. But im planning to set my computer to mine litecoin and my Erupters to mine bit coin at the same time.
I don't mine using my computer as it always on, mining or not.
I figure better mine some now and not wait until it gets harder. Maybe in the feature it will be worth something.
