I find XCN to be a good stand-by for mining.
As comparing SIGT to XCN... XCN does pay out a bit more than SIGT currently (with my systems; its XCN $68.87 vs SIGT $65.84).
However that said, SIGT seems it will go up some more, and thus have better value (and currently can be traded), until the difficulty rises, Block 30,000 I believe.
At which case, then XCN may be the better deal to mine on a daily basis.
Let see for HR and price:
my HR total:
13*gtx 1060 3gb, 1*gtx 1070 8gb.
for xcn: ~180mh/s. can mine ~2700xcn`s. current price = 295 sat`s(bter). 2700 * 0.00000295 = 0.007965 btc.
for sigt: ~240mh/s can mine ~ 800 sigt`s. current price = 1464 sat`s (cryptopia). 800 * 0.00001464 = 0.011712 btc.
so, how you calculate your profit?
XCN: ~140 Coins/Hr = 3360 Coins/Day * 0.1339 (XCN to CNY) / 20770 (CNY to BTC) = 0.021661242 BTC => @ $3,150 USD to BTC = $68.23
SIGT: ~ 57 Coins/Hr = 1368 Coins/Day * 0.0000146 (SIGT to BTC) = 0.0199728 BTC => @ $3,150 USD to BTC = $62.91
Note, this is using BTC38 (when it is working) and not Bter.
But yes, I would say at this time would be better to go with SIGT before the 30,000 block kicks in and the increase of difficulty.
Afterwards, depends on the price of SIGT, to determine which is better to mine (and when BTC38 is working properly).
Update:
Missed up originally with a 0.0000164 instead of 0.0000146 with SIGT to BTC.
