So make a bid on Nicehash with your 0.05 limit, and it should stay pretty consistent.
got tired of bidding wars 
will go back to that when nicehash stops blocking fixed orders
and before someone suggests miningrigrentals, the absurd price per TH/s for the rigs already present there is not justified by market conditions
Well, current price renters already paying for Quark on HashTap is 0.066 BTC/TH, but available is only 0.05 TH/s, so Your request for 2 TH/s will probably lead to price increase and sure not fitting offered 0.05 BTC/TH.
Anyhow, good luck finding it.
Didn't know about HashTap, thanks for lead! It has some few hundred GH/s available now, i can work with that.
Also, i can work with smaller orders too, not necessarily 2 TH/s in one order.
