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?
