I have detected a very considerable profit drop when mining.
About 2 months ago, 1 vga 3090 - 115 hr, generated 0.10 in 30 days.
Now I have 2 vgs 3090, 234 hr, and I generate 0.10 in 20 days.
From what I see here: Ethereum Mining Profitability Chart
The rate is even higher …
Why so much difference?
I use HIVEON and PHOENIXMINER.
Do I have to change something to get more performance?
With a single 3090, it has gone from those 30 days of generating 0.10 to needing 45.
