An RTX 3090 can mine roughly $0.50 to $1.20+ per day, but this varies wildly with crypto prices, electricity cost (around $0.10/kWh), and algorithm, often yielding low profit after expenses, sometimes only a few cents or even negative profit on popular coins like Ethereum (now Proof-of-Stake), but potentially better on newer coins like Dynex or Quai, though these also fluctuate significantly.
The RTX 3090 has an impressive 121 MH/s hash rate. But it has double the price tag as a RTX 3080 which manages 98 MH/s. Not great economy of scale here.
NVIDIA RTX 3090 - Hashrate. The estimated profitability for the NVIDIA RTX 3090 is currently $1.55 per day before accounting for electricity costs. With an electricity rate of $0.10 per kWh, the estimated daily profit would be around $0.97.
How Long Does It Take to Mine 1 Bitcoin? As of December 2025, the reward for mining one block is 3.125 bitcoins. It takes the network about 10 minutes to mine one block, so it takes about 10 minutes to mine 3.125 bitcoins.
Taking a buy-and-hold position in Bitcoin five years ago would have delivered massive returns for investors. As of this writing, Bitcoin is up 962.3% over the period. That means that a $1,000 investment in the token made half a decade ago would now be worth more than $10,620.
One person mining 0.000065 BTC (four RTX 4090s on Oct. 6, 2024, using NiceHash) per day would take more than 42 years (about 15,384 days) to earn 1 BTC, all else, such as block rewards, hash rates, and pool payouts, remaining the same.
Top 10 GPUs For Mining
Mining can still be profitable in 2025, but not for everyone. It depends on several factors: Low electricity costs: Miners with access to cheap power have a clear advantage. Efficient hardware: Modern ASICs and optimized setups are essential.
NVIDIA GeForce RTX 3090 Ti
NVIDIA GeForce RTX 3090 Ti is a high-performance gaming, 3D rendering and cryptocurrency mining GPU. Because of its balanced features of power architecture with expanded memory capacity, it has become a favorite choice for miners looking for efficiency and profitability.
In addition, the RTX 3090 features 328 tensor cores, 96 ROPs, and 82 RT cores. Not only is this the most powerful NVIDIA graphics card yet, it's the only one in the new GeForce RTX 30 series to support NVLink. It also requires 350W of power and a PSU with a minimum power rating of 750W.
Since the introduction of the ASIC miners, GPUs cannot mine bitcoin competitively anymore. As a result, investors shift to other coins they can still mine profitable. Joining mining pools can help GPU miners maximize their earnings when mining altcoins by sharing rewards and reducing risks.
As to whether mining crypto on NiceHash is profitable, profitability depends on electricity costs, hardware efficiency, and market demand spikes, making it viable for GPU sellers via tools like QuickMiner but less so in high-cost regions without optimization.
NVIDIA GeForce RTX 3090 can generate more than 10.69 USD monthly income with a 95.52 MH/s hashrate on the CFX - Octopus (NBMiner) algorithm.
Put it another way, GeForce RTX 5090 is 133-237% faster than RTX 3090 here.
Prolonged high temps (over 85°C) can: Throttle performance: GPUs reduce speed to cool down, lowering frame rates.
Yes. Crypto mining can be profitable, but there are factors miners need to consider, including electricity costs, mining difficulty, and market conditions. All these can significantly impact profitability. Electricity expenses play a crucial role as mining operations consume substantial power.
Currently, miners earn a reward of approximately 3.125 bitcoins every 10 minutes. This means that, on average, 0.3125 bitcoins are mined per minute across the entire network. To put it another way, one bitcoin is generated roughly every 3.2 minutes when aggregating mining activity globally.
British bank Standard Chartered projects that Bitcoin's price will reach $500,000 in 2030. Multiple prominent figures, including Coinbase CEO Brian Armstrong and Block CEO Jack Dorsey, have expressed their belief that it could reach $1 million or more.
However, mining 1 Bitcoin can take significantly longer depending on several factors. For most individual miners, mining 1 Bitcoin could take several months with average hardware. This is why many miners join mining pools, which increase their chances of earning rewards more consistently.
Gaming Performance
The RTX 4090 dominates in 4K gaming, comfortably hitting over 100 FPS in titles where the RTX 3090 hovers below 90 FPS. DLSS 3 frame generation further widens the gap, making gameplay noticeably smoother and more immersive.
