Why You Need a Mining Pool
Bitcoin mining works by having computers compete to solve a mathematical puzzle. The winner gets to add the next block to the blockchain and earns the block reward, currently 3.125 BTC per block (after the April 2024 halving).
The probability of any single miner winning this competition is proportional to their share of the total network hashrate. The total Bitcoin network hashrate in 2026 exceeds 700 exahashes per second. A single ASIC miner at 200 TH/s has an infinitesimally small chance of winning a block on its own, statistically, you might wait decades.
Mining pools solve this by combining hashpower from thousands of miners. When the pool finds a block, the reward is split proportionally based on each miner's contributed hashrate. Payouts become regular and predictable rather than random and rare.
How Pool Fees Work
Pools charge a percentage fee on your earnings, typically 0% to 4%. Higher fees can be justified by better reliability, additional features, or payout flexibility. The fee structure matters but should not be the only consideration, pool reliability, uptime, and payout policy are equally important.
Common payout methods:
- PPS (Pay Per Share): The pool pays you a fixed amount per share submitted, regardless of whether the pool finds a block. Predictable income, pool absorbs variance. Higher fees.
- PPLNS (Pay Per Last N Shares): Rewards based on shares submitted in a rolling window of the last N shares when a block is found. Lower fees, slightly more variance, better for consistent miners.
- FPPS (Full Pay Per Share): Like PPS but includes transaction fees from blocks in the payout calculation. Widely used by major pools.
Best Mining Pools in 2026
Foundry USA
Foundry USA is the largest Bitcoin mining pool by hashrate as of 2026. Operated by Foundry Digital, a subsidiary of Digital Currency Group, it has grown rapidly due to its competitive fee structure and focus on institutional and professional miners. US-based miners benefit from low latency and regulatory familiarity. FPPS payout model means you receive a share of both block rewards and transaction fees.
AntPool
AntPool is operated by Bitmain, the largest ASIC manufacturer. It has been one of the top pools by hashrate since 2014. Supports multiple payout methods including PPS+, PPLNS, and SOLO. AntPool's integration with Bitmain hardware makes it a natural choice for Antminer operators. The dashboard is comprehensive, with detailed real-time stats.
F2Pool
F2Pool is one of the oldest and most established mining pools, operational since 2013. It supports Bitcoin, Litecoin, Ethereum Classic, and other coins. PPS+ payout model. Strong reputation for reliability and transparency. A solid choice for miners who prefer a pool with a long track record.
ViaBTC
ViaBTC has been operational since 2016 and supports multiple cryptocurrencies. Offers PPS, PPLNS, and SOLO payout options. Known for its mining profitability switching features and a clean interface. Available globally and supports miners in North America, Europe, and Asia.
Braiins Pool (formerly Slush Pool)
The world's first Bitcoin mining pool, operational since 2010. Operated by Braiins, creators of the open-source Braiins OS firmware for ASIC miners. Smaller hashrate than the top pools but a strong reputation for transparency and the community-oriented team behind it. Braiins OS can improve miner efficiency by 5–15% through advanced tuning, making the combination attractive for technically capable miners.
Pools to avoid: BTCC Pool and Eligius, once prominent pools, are no longer operational. Do not attempt to point hardware at these addresses. Always verify a pool is active and maintained before configuring your miner.
How to Connect to a Mining Pool
Once you have chosen a pool and created an account:
- Log into your ASIC miner's web interface (typically via its IP address on your local network)
- Navigate to the "Miner Configuration" or "Pool" settings
- Enter the pool's stratum URL and port (provided by the pool, e.g.
stratum+tcp://btc.foundryusapool.com:3333) - Enter your pool username (usually your pool account username or wallet address) as the worker name
- Save settings and restart the miner
- Log into the pool dashboard to confirm hashrate is being received
Most pools recommend setting up two or three pool addresses in order of priority. If the primary pool goes offline, the miner automatically switches to the backup, preventing downtime.
Decentralization and Pool Choice
A healthy consideration when choosing a pool: Bitcoin's security depends on no single entity controlling too much of the network's hashrate. When any pool approaches 50% of total hashrate, it raises centralization concerns. Supporting smaller pools like Braiins, OCEAN, or other independent operators helps maintain network decentralization, which many Bitcoin miners care about.
