I've noticed Goldcoin network hashrate went from 25MH/s to 70MH/s and still rising while diff isn't at bottom.

Also it's not in top altcoin to mine, diff not at bottom so it's not the multipools causing this (I'm at trademybit/hashco.ws and I didn't see them mine this for a minute).

Does anyone know what's happening. Is there some INFO about GoldCoin I'm missing?
