I'm afraid mining is over for this coin now! You can mine signatum or DGB, they are both two underrated coins.
signatum has some difficulties now which affects on their cost in a long run perspective!
look, first we have a huge scandal inside the team, when one of them desided to split
second, now we have a problem with Cryptopia with wallet, cause there some problem with withdrawal
that are not good news for Signatum(, but I hope then can fix it and earn trust of investors once again
as for DGB - it has so big spikes )) but I agrree with on it, that is a good coin to watch and mine
LoL I take a gamble- i mine ZEC or DGB when they are beaten to the ground. I was mining DGB when it was around 3-4 $ a day but I was accumulating coins.
Now recently I switched and changed them and it turned to be a profit around 7-7.50$ a day.
My ROI on my Card was 211 days single 1080ti - but I've paid it within 60 days. It's fair bit of luck as well because BTC is ripping though everything lol
My theory is - i accumulate coins that are best mined with 1080ti -so atleast card is being to used to full potential. (I'ts like buying shares of good company during a downturn) then selling during uptrend.
