What is nearly impossible to predict is WHEN it will level off. It seems to be starting to now, but this could be a hiccup.
It's not going to level off anytime soon. Any leveling off you see is just temporary variation. Tons more hashpower is coming online in the following months. A few days of low increase means nothing in the big scheme of things. 6 months from now I'm going to laugh so hard at anyone sayinig it's leveling off now.
