Dual .mining with correct dcri was always profitable on 1080/ti. Because 1080/ti has a lot of cpu power which is not used by daggerhasimoto algo.
Only if by "profitable" you mean more then the electricity cost)
No I mean that it have +/- the same profit as zec or other algos.
LOL, SIGT wishes. Have you actually tried to mine SIGT or are you preaching from whattomine here?
"profitability" is a nonsense unless your coins is sold immediately after being mined (not even after 24 hours).
In my case, I actually mine hush and sigt with 2 similar rigs, hush was slightly more profitable over the last 24 hours, but I don't sell them, same for sigt. So only the future will tell which coin was more profitable.
I used to mine LBC when it was non "profitable" compared to ZEC, and guess what : when I sold my coins, the LBC I mined were suddently a lot more profitable than ZEC.
I think all miners combine both methods: 1) sell after mine in a couple of days - a lot of shit pump dump coins like cxt, ctic2 ... 2) hold until the price "to the Moon". Depends on my inner vision of the coins future.
