How much did the rig cost, what is your electricity cost, how much does it yield on avg? There are so many factors. I remember a friend who built a rig for about 5K USD, mined a shitcoin, somehow that shitcoin was worth $60, he made a killing from that. Instant ROI in about a month.
2800 TRY per card (amazon deal) + 2.5k TRY for the rig
