Two things are true at once: mining is a real, legitimate way blocks get produced, and most of the mining content aimed at beginners is either marketing for hardware nobody needs or an outright scam. This hub starts with the mechanics, then the honest math, then the real pools — in that order, on purpose.
Three pools we actually researched — including one lookalike scam domain we found along the way.
Pool size, fee structure, and whether a genuine affiliate program exists all vary. None of this is a ranking — match the pool to what you actually need, and always confirm you are on the official domain before entering a payout address.

Foundry USA Pool
Institutional-grade Bitcoin mining pool operated by Foundry Digital (a Digital Currency Group company); aggregates hashrate under an FPPS payout model and is currently the largest Bitcoin pool by network share.
Review-only candidate; no affiliate relationship exists. Use as an educational case study on institutional mining and pool centralization, not as a signup recommendation — most readers cannot access it.
Full risk details
Best for
Large-scale/industrial mining operations and public mining companies able to pass Foundry's KYC/AML onboarding and meet its institutional scale requirements.
Avoid if
You are a home or hobbyist miner — Foundry USA has no self-serve retail sign-up; onboarding requires direct contact with Foundry's team plus identity/compliance verification.
Risk note
At roughly a quarter to a third of total Bitcoin network hashrate, Foundry USA's size feeds the pool-centralization/censorship-resistance debate that applies to any single pool approaching dominant share. Its widely reported 0% pool fee is generous, but payouts still run through FPPS mechanics (rewards net of a smoothed average of block subsidy + transaction fees, with outlier blocks excluded), and retail miners cannot access it at all without clearing institutional KYC.
Score rationale
Hashrate share (~26-30%, #1 pool) confirmed via multiple mid-2026 aggregator sources cross-referencing mempool.space/btc.com-style distribution data, dated July 2026. FPPS payout mechanics confirmed directly on Foundry's own knowledge base. The 0% fee figure is consistently reported by third-party pool trackers (e.g. miningpoolstats.net) rather than pulled verbatim from Foundry's own numeric disclosure, so it is flagged as third-party-corroborated. No genuine public affiliate/referral program was found anywhere on foundrydigital.com — onboarding is KYC-gated and institutional-only.
Large multi-coin Bitcoin mining pool operated by Bitmain (the dominant ASIC manufacturer); offers a choice of PPLNS, PPS+, and FPPS payout schemes and is consistently one of the two largest Bitcoin pools by hashrate.
Caution candidate; no verified affiliate relationship. Any coverage must warn readers to confirm they are on antpool.com before entering any information, given the lookalike domain found during research.
Full risk details
Best for
Miners already running Bitmain Antminer hardware who want tiered payout-scheme choice and are comfortable with a Bitmain-affiliated, China-linked pool operator.
Avoid if
You want fee-model simplicity (three different schemes at differing fee levels can confuse beginners), you're wary of hashrate concentration inside one ASIC manufacturer's ecosystem, or you land on any site other than the official antpool.com claiming to run an 'AntPool affiliate program.'
Risk note
AntPool's own published fee schedule spans 0% (PPLNS, no transaction-fee share), 2.5% (PPS+), and 4% (FPPS) — picking the wrong scheme materially changes take-home pay on already-thin mining margins. Separately, this research surfaced a lookalike domain ('antpool.digital') advertising an unrelated 'arbitrage bot affiliate program' that is NOT antpool.com — a textbook impersonation risk worth calling out explicitly to readers.
Score rationale
Hashrate share (~18-19%, consistently #2) confirmed via mid-2026 aggregator sources cross-referencing mempool.space/btc.com-style distribution data, dated July 2026. Fee tiers (PPLNS 0% / PPS+ 2.5% / FPPS 4%) confirmed via AntPool's own official help-center domain, corroborated by an independent 2026 pool comparison. A dedicated search for a genuine antpool.com affiliate/referral program found no confirmed program on the real domain — the only 'affiliate' page located was on an unrelated, suspicious lookalike domain — so affiliate is set to false and that domain is flagged as a risk rather than treated as a program.
Multi-coin mining pool (BTC plus others) offering a choice of PPS+ or PPLNS payout, with one of the more transparent public fee pages in the industry and a live, documented referral-commission program.
Approved candidate pending WWC integration; genuine referral program confirmed live on ViaBTC's own site. Must be surrounded by mining ROI/profitability and fee-scheme (PPS+ vs PPLNS) education before activation, consistent with WWC's other mining content.
Full risk details
Best for
Intermediate-to-advanced miners comparing payout-scheme tradeoffs (steady PPS+ vs. variance-exposed PPLNS) who want a pool with an openly published fee page instead of fees buried in support tickets.
Avoid if
You want the lowest possible fee (ViaBTC's 4% PPS+ is on the higher end versus Foundry's 0% or AntPool's cheaper tiers), or you're not comfortable that ViaBTC's parent company also operates an affiliated crypto exchange.
Risk note
Published fee is 4% under PPS+ (steady payouts) or 2% under PPLNS (variance-based, dependent on the pool actually finding blocks); on already-thin mining margins, that fee gap plus electricity and hardware costs can be the difference between profit and loss. New PPLNS miners in particular can see payout volatility during any stretch of bad luck between blocks.
Score rationale
Hashrate share (~9-13%, typically #4 among BTC pools) confirmed via mid-2026 aggregator sources cross-referencing mempool.space/btc.com-style distribution data, dated July 2026. Fee schedule (PPS+ 4%, PPLNS 2%) confirmed directly via ViaBTC's own official pricing page, fetched July 2026. Referral program (10% commission for 12 months at the general tier, 20% permanent at the 'ambassador' tier, paid ongoing on referred miners' service fees) confirmed live and currently active directly via ViaBTC's own official referral page, same date.
