do i have to say this in every fucking thread? without litecoin and other altcoins, bitcoin mining would cease to be profitable. alt coins are necessary evils because they spread the hashing power out accross multiple networks, allowing everyone to profit in some way shape or form. without litecoin and altcoins. you could multiply the difficlut by 5 and decrease your profit by 50 percent. those are just guestimates of course.
