THERE IS A WALL!!! (edit: or is it a floor? I always get those two mixed up)
Bid Price (BTC) Amount (XPY) Total (BTC) Sum (BTC)
0.00000001 50250.00000000 0.00050250 0.001
that's just a buy order. a nice way of saying FU to me, considering they wanted to pay 1 satoshi per xpy...

There is a sell order that keeps changing it's mind as well. right now:
Ask Price (BTC) Amount (XPY) Total (BTC) Sum (BTC)
0.07000000 1.44900000 0.10143000 0.101
$25, that's pretty much saying FU too

Got a couple of bitmain S1's I could dig out - worth the effort?
Definitely. NiceHash now pays more than twice as much as BTC mining. Get it while you can but watch for when it drops.
Edit: sorry for peddling my own site but here is a quick overview of rental prices, SHA256 column:
http://cryp.today/currentAs you can see NiceHash is paying really well. Straight BTC mining is ~0.013 per TH/s per day, NH is paying more than triple now.
