So my observation, with Antmine you get bigger payment but you need to wait longer while Unimining you get payment like every 10-15mins.
I got 185mhs(ETH )and 7000mhs(XVG) on 6x rx570. And so far I got 84XVG in my wallet and I still have 13XVG in my Unimining account.
I prefer Unimining, I did not experience any problems with unimining, I've used the 5766 port and declared the c=XVG value. I'm not sure if that makes a difference.
Either way you can't go wrong, I just prefer seeing continuous payment compared to waiting for hours.
Thanks man! You do help me solve the unimining huge rejected share problem!
I use port 5770 which caused 10+% rejected share and I change to port 5766 which only 0-1% rejected share.
Hope other can solve the same problem by changing the port.
