2miners is showing over 51% on miningpoolstats… should we be worried?

I saw the jump in RVN’s value about an hour and a half ago and was about to make a post where I speculated that RVN is on a knifes edge where any large buy order shoots the value up massively. Before writing the post though, I checked out miningpoolstats and noticed the huge jump in 2miners hashrate.

My first thought is that we should be worried about a 51% attack considering that 1TH/s just popped up out of the blue. But then I started wondering if maybe someone put in a massive buy order at nicehash or something to score some fat sacks… maybe an exchange that is preparing to list the coin?

Thoughts?
