Unfortunately, you will not be able to profitably mine an alternate altcoin with your 4GB cards once the 4GB DAG limit hits. For the math behind this assertion please see our more in-depth article here.
Tl;dr – Seriously…you will not be able to profitably mine something else with 4GB cards for all but the early days of 2021.
Don’t grab the hot potato
So whatever you see out there for sale, keep in mind that there are literally millions of 4 GB cards out there that will either be looking to mine something else or for a new home. I’m strongly advising that you do not buy 4 GB cards for mining under any circumstances. There are a ton of people that will tell you that you’ll ROI so fast that it’s worth gamble, and they might be right, but there’s a greater chance that you’ll be stuck with a bag of hot potatoes.
LolMiner’s “Zombie Mode” for ETH mining with 4GB cards.
The early days of 2021 have been saved for 4 GB cards by an inventive workaround that allows for 4 GB GPUs to continue to mine Ethereum, albeit with steadily decreasing profitability.
Currently, the hashrate on Zombie mode is dropping 7% every 4 days. All the while ETH value is appreciating rapidly and prompting increased mining investment from current and new miners. These miners are deploying newer hardware. So, while we see hashrate from 4GB ASICs and GPUs peeling off, with accompanying difficulty drops, we are seeing miners coming online at the same pace and making up for the drop in hashrate.
