I don't know enough to comment on that.
Though if I were to take a guess, I'd say it's simply market forces at work - no asset value rises indefinitely that fast. ETH has had a HUGE price increase over the last month - it's almost surprising it hasn't had a deeper retracement - though perhaps the corrective wave is just flatter. Inevitably, with all the developments taking place in the Ethereumsphere, price shall continue for another upward wave sooner or later...
Sounds good cheers to that
