SPREAD THE HASHRATE. GETTING EVER CLOSER TO 51% ON F2POOL. LET'S NOT DESTROY A VERY GOOD PROJECT!!
63.3 % of Known Hashrate. Or ~33% of Net hashrate. Total Net hashrate 11 TH. 
There is a large FPGA farm on F2Pool. Jmining, who has mined over 6 millon RVN and has sold 0 coins. I think Jmining has about 1.5 TH of the volume. Doesn't seem to be a problem at all.
I'm more afraid that the x16rv2 algorithm can be rented on Nicehash. Now there is 1.5 TH, but when the rental price increases there will be several times more. This is a real danger to the network, allowing a 51 percent attack.
