After 48 hours using 5 Radeon RX Vega 56 - 8GB HBM2 2048bit on my first rig i got 2100 ETN and an electricity consume of 6-7$ ... on this moment those 2100 are approx 82$ BUT they had an approx 30% grow in the last 24-36 hours ...At the end .... a profit of 38$/day with an investition of max 3500$ ...
Please let me know if you know another coin with a higher ROI mineable with a rig like mine
