What to Mine with a 4GB GPU in 2023?

In 2023, cryptocurrency mining is still a hot topic, but for those with older or more limited hardware, such as a 4GB GPU, the options are narrowing. Many larger coins, such as Ethereum, have already transitioned or are transitioning to Proof-of-Stake, meaning that they are no longer mineable using GPUs. This leaves miners with smaller setups, like 4GB GPUs, in a bit of a bind. However, there are still some opportunities available for those who are willing to be creative and look for less competitive coins.

Why 4GB GPUs Are Still Relevant for Mining in 2023

Though 4GB GPUs were once the standard for mining, they have been largely outpaced by 6GB, 8GB, and even 12GB GPUs. Most of the more profitable coins require higher memory capacity to handle their increasingly large DAG sizes. That said, 4GB GPUs can still be used to mine smaller, less popular coins that haven’t yet seen massive increases in DAG size or have developed optimizations to accommodate smaller GPUs.

The critical consideration when mining with a 4GB GPU in 2023 is finding the right coin with the correct algorithm. Some of these coins might not be as valuable or well-known as Ethereum or Bitcoin, but they can still generate profits, especially if you're working with multiple GPUs or in regions with cheaper electricity.

Top Coins to Mine with a 4GB GPU in 2023

Here are some cryptocurrencies you can still mine with a 4GB GPU:

1. Ethereum Classic (ETC)
   Ethereum Classic continues to be a popular option for those with 4GB GPUs, as its DAG size remains smaller than Ethereum's ever was. With Ethereum having transitioned to Proof-of-Stake, Ethereum Classic has emerged as one of the best options for smaller miners. While its profitability is lower compared to Ethereum in its heyday, it’s still a viable coin to mine in 2023.

2. Ravencoin (RVN)
   Ravencoin uses the KAWPOW algorithm, which is well-suited for 4GB GPUs. The coin has a solid community backing and a number of use cases, including token creation and asset management. It’s an attractive option for those with limited hardware because of its relatively low DAG size and consistent profitability.

3. Ergo (ERG)
   ERG is a coin that utilizes the Autolykos v2 algorithm, which is memory efficient and suitable for GPUs with smaller VRAM. The key advantage of Ergo is that it is designed to be mineable by both large and small-scale miners, with a lower barrier to entry compared to other coins. In 2023, Ergo is one of the few coins that remains profitable for smaller GPUs, especially if you have access to cheap electricity.

4. Firo (FIRO)
   Firo, formerly known as Zcoin, uses the MTP algorithm which focuses on decentralization and memory hardness. This algorithm was specifically designed to be ASIC resistant and more accessible for smaller miners. Firo’s lower DAG size makes it a feasible option for 4GB GPU miners in 2023.

5. Vertcoin (VTC)
   Vertcoin utilizes the Lyra2REv3 algorithm, which is GPU-friendly and resistant to ASIC mining. This makes it a good option for miners who want to keep using their older GPUs. Vertcoin’s community is dedicated to decentralization, making it an appealing choice for those who want to support smaller, decentralized blockchain networks.

6. Beam (BEAM)
   Beam uses the BeamHashIII algorithm, which is designed to be more memory-efficient than other mining algorithms. Beam has privacy features similar to Zcash and Monero, which adds value to the coin and makes it a solid option for those looking to mine with 4GB GPUs in 2023.

Factors to Consider When Mining with a 4GB GPU in 2023

While mining with a 4GB GPU is still possible, it’s essential to consider several factors to ensure profitability:

• Electricity Costs: One of the most significant factors affecting your mining profits is the cost of electricity. In regions where electricity is expensive, mining with older hardware might not be profitable. However, if you’re in a region with cheaper power, 4GB GPU mining can still yield a profit.

• Mining Pool Fees: Joining a mining pool is often necessary for smaller miners to have a consistent payout, but pools charge fees. Make sure to choose a pool with reasonable fees that won’t eat into your profits.

• Algorithm Efficiency: Different coins use different algorithms, and some are more memory-intensive than others. Opt for coins with memory-efficient algorithms that don’t push the limits of your 4GB GPU.

• Hardware Wear and Tear: Mining can be demanding on your hardware, and older GPUs might not last as long under the constant strain of mining. Be sure to monitor your GPU’s temperature and performance to avoid burnout.

Mining Profitability in 2023

When considering mining with a 4GB GPU in 2023, it’s crucial to understand that you won’t be making the kind of profits that miners did in 2021 or early 2022. However, that doesn’t mean mining is unprofitable; it simply means you need to manage your expectations and be strategic. With electricity costs rising in many parts of the world, 4GB GPUs will need to mine more efficient coins to stay in the black.

Here’s a table showcasing the current profitability of some coins mentioned above when mined with a 4GB GPU:

Coin	Algorithm	Approx. Daily Profit (USD)	Electricity Cost (USD)	Net Profit (USD)
Ethereum Classic	Etchash	$1.50	$0.50	$1.00
Ravencoin	KAWPOW	$1.20	$0.50	$0.70
Ergo	Autolykos v2	$1.10	$0.50	$0.60
Firo	MTP	$1.00	$0.50	$0.50
Vertcoin	Lyra2REv3	$0.90	$0.50	$0.40

Future Outlook for 4GB GPU Mining

The future of 4GB GPU mining is uncertain as DAG sizes continue to grow and more coins move towards Proof-of-Stake. However, there will always be smaller coins and new algorithms that might still support older GPUs. Mining enthusiasts should stay up-to-date on developments in the cryptocurrency space to ensure they’re making the most out of their hardware.

Some new, smaller projects, especially in the privacy coin space, might offer opportunities for 4GB GPU miners in the future. However, expect the pool of mineable coins to shrink over time.

In conclusion, while the heyday of 4GB GPU mining is over, there are still opportunities to be found for those who are willing to put in the effort. With careful research and an understanding of the factors that affect profitability, it’s possible to turn a profit even with older hardware in 2023.
