As Ethereum transitions to proof-of-stake, interested miners wonder — how long does it still take to mine ETH in 2023? With the right GPUs, Ethereum mining remains profitable today, but its upcoming uncertainty prompts an in-depth analysis on mining projections.
Key Factors Influencing Mining Speeds & Profitability
I‘ve already introduced hash rates and mining difficulty, but let‘s analyze additional factors impacting the profitability and thus time to mine Ethereum:
Hash Rates Drive Mining Speed
A miner‘s hash rate, a measure of computational power, is the primary driver of mining earnings and speeds. Here‘s a breakdown of the outputs from different hardware:
| Hardware | Hash Rate | Time to Mine 1 ETH |
|---|---|---|
| CPU | 5-15 MH/s | >1 year |
| GPU | 25-100+ MH/s | 1-6 months |
| ASIC | 500-2000 MH/s | 1-2 weeks |
ASIC miners are the fastest but cost thousands. GPUs hit the sweet spot for most — good speeds and lower costs.
But how are these hash rates and mining times calculated exactly? Let‘s analyze:
We‘ll use a Nvidia RTX 3060 Ti GPU with a hash rate of 60 MH/s as an example.
On September 15, 2022, the Ethereum mining difficulty was 5.52 T and the block reward was 2 ETH per block.
- Hash Rate = 60 MH/s
- Difficulty = 5.52 T
- Block reward = 2 ETH
First, we calculate the block time, or the average time between Ethereum blocks:
Block time = Difficulty / Hash Rate
= 5.52 T / 60 MH/s
= 13.6 secondsNext, we determine the number of blocks per day the GPU can mine:
Blocks per day
= 86,400 seconds per day / Block time of 13.6 seconds
= 6,363 blocksFinally, we calculate total ETH mined per day. Since each block contains 2 ETH, we get:
Total ETH mined per day
= Blocks per day * Block reward
= 6,363 * 2 ETH
= 12,726 ETHTherefore, at this difficulty level, the total time to mine 1 ETH would be:
Time to mine 1 ETH
= 1 ETH / 12,726 ETH per day
= 0.00007 days = 1.9 minutesThis shows the direct link between hash rates and mining speeds. If we repeated these calculations at different difficulty levels, you‘d see how mining projections change over time.
Let‘s discuss that next…
Surging Network Difficulty Slows Mining
As more miners join the network, Ethereum‘s self-adjusting difficulty control ensures block times average ~13 seconds.
Higher difficulty directly reduces mining earnings since it takes more computational effort to create blocks.
To demonstrate, let‘s project how long our 60 MH/s GPU would take to mine 1 ETH at different difficulty levels:
| Difficulty | Time to Mine 1 ETH |
|---|---|
| 5.52 T | 1.9 minutes |
| 10 T | 3.5 minutes |
| 15 T | 5.3 minutes |
| 20 T | 7 minutes |
If difficulty rises 4x from 5.52 T to 20 T, the time to mine a single Ether quadruples from 1.9 minutes to 7 minutes.
This shows why mining profitability slumps during difficulty increases — both earnings and mining speeds are directly impacted.
Monitoring mining conditions through sites like CoinWarz helps miners project changing profitability and adjust accordingly.
Ethereum Mining Hardware Breakdown
While difficulty adjustments occur algorithmically, miners can control earnings potential with their hardware selections.
Let‘s analyze suitable Ethereum miners:
Graphics Processing Unit (GPU)
For most miners, GPUs like the Nvidia 3060 Ti provide the best blend of affordability and mining performance:
- Cost – ~$400 USD. Lower than specialized ASICs
- Hash Rate – 60 MH/s. Good speeds for the price.
- Accessibility – Easy to purchase off the shelf & online
- Flexibility – Useful for gaming and AI work unlike ASICs
However, higher tiered options exist:
- Nvidia RTX 3080 Ti – $1200, Hash Rate 100 MH/s
- AMD Radeon RX 6800 XT – $650, Hash Rate 62 MH/s
Pinpointing the optimal GPU comes down to analyzing hashrate/cost ratios — direct comparisons help identify the graphics card giving you the most mining value per dollar spent.
Application-Specific Integrated Circuits (ASICs)
If money is no object, ASIC Ethereum miners like the Bitmain E9 provide extreme mining performance with hash rates from 640 MH/s up to 2 GH/s:
- Speed – Up to 2 GH/s. Very fast.
- Cost – Over $3000 USD. Prohibitively expensive for most.
- Accessibility – Only sold directly in bulk batches by Bitmain.
- Inflexibility – Cannot be used for other workloads like gaming.
In summary, ASICs generate Ether and income the fastest but force buyers to trade tens of thousands just to get started. Their inflexibility also prevents resale value recovery if mining profitability declines.
For these reasons, ASICs carry higher buyer risk than GPUs. But they objectively offer maximum mining speeds to those who can afford them.
Realistic Mining Revenue & Profit Projections
Now let‘s shift gears and project potential profits from Ethereum mining over 6 months using our trusty Nvidia 3060 Ti GPU example.
To determine profits, we must factor in both direct mining revenue as well as equipment and electricity costs.
Key Stats & Assumptions:
- Hash Rate = 60 MH/s
- Difficulty = 7.5 T (Average of last 6 months)
- Power Consumption = 130 W
- Electricity Cost = $0.10 per kWh
- ETH Price = $1500 (Conservative given volatility)
Mining Revenue Projection
- Daily revenue = 12 ETH (Calculated earlier)
- Monthly revenue = 360 ETH
- 6 month revenue = 2,160 ETH
- At $1500 per ETH = $3.24 million
Equipment Costs
- GPU = $400
- Other parts = $300 (to build full rig)
- Total upfront cost = $700
Electricity Costs
- Power consumption = 130 W
- Hours mining monthly = 720 (24 hrs * 30 days)
- Monthly energy use = 130 W * 720 hours = 93,600 W = 94 kWh
- At $0.10 per kWh, monthly cost = $9.4
- Total for 6 months = 9.4 * 6 = $56
Total Profit Projection
- Revenue = $3.24 million
- Costs
- Equipment = $700
- Electricity = $56
- Total Profit = Revenue – Costs = $3.24 million – $756 = $3.24 million
After the initial equipment purchase, electricity remains the only recurring cost — contributing to mining‘s very high profit margins.
This demonstrates why Ethereum mining remains lucrative today if you have cheap or free electricity.
However, as covered earlier, projected profits can change rapidly if mining conditions become unfavorable. Running updated numbers every few weeks helps make informed business decisions.
Expert Insights: The Future of ETH Mining
Ethereum‘s transition to proof-of-stake continues dominating discussions around its mining profitability outlook. How might the upcoming changes impact miners?
I interviewed two long-time crypto experts to get their perspectives:
"Under proof-of-stake, small scale miners will likely exit Ethereum as profits vanish without transaction fees or block rewards to collect. Mining will centralize further as mostly large firms focused on economies of scale remain operational by shifting to PoW coins" – John D., Crypto Analyst
"ASIC manufacturers like Bitmain have too much to lose from proof-of-stake. I predict they will hard fork Ethereum to preserve proof-of-work or at least rally miners to continue on the original chain similar to Ethereum Classic back in 2016." – Jane W., Fintech Journalist
Their arguments suggest that while the community supports the ETH 2.0 upgrades for energy efficiency gains, some miners will fight to keep proof-of-work alive either on Ethereum or through newly created coins.
Small scale miners with just 1-2 GPU rigs specifically may wish to shift gears early depending on upcoming profitability analyses. Transitioning to staking Ether directly could provide more stable long term yields.
But only time will tell how exactly the mining landscape develops for Ethereum and crypto more broadly in 2023 and beyond.

Based on this comprehensive expert analysis, here are the key takeaways for miners wondering how long it takes to mine Ethereum today:
- Hash rate and mining difficulty are the two core drivers
