Overview

Braiins operates the world's longest-running Bitcoin pool (mining since 2010, as Slush Pool) plus firmware and the new Hashpower hashrate market [3][4]. The operator of the pool is Braiins Mining Limited, a BVI company named in its own terms, alongside Czech operating entities [1]. This is the only pool in our ranking that now sells hashrate directly - through a live order book and self-serve contracts [4].

What you can rent

Yes - actually rentable hashrate, verified live. The Braiins Hashpower order book (public beta since January 2026) returns real matched bids and asks on a public API - best ask around 0.47 BTC per EH-day at check [3]. You can bid in the spot market, buy guaranteed-delivery contracts (1 PH/s to 2 EH/s for 7 days to 2 months, launched publicly in August 2026) [5], or buy solo-mining packages where you keep an entire block reward if one lands in your window [6] - the launch post promised "the full block reward of over three bitcoin" [7]. Pool mining is the other half: 2.5% FPPS, free Lightning payouts, 0% fees with BraiinsOS [3].

Contract & terms

Pool terms: Braiins Mining Limited (BVI company 2038702), BVI law and courts, with a voluntary commitment not to do business with OFAC-sanctioned parties [1][2]. Hashpower signup uses Telegram plus email with 2FA - no ID-KYC - but "we screen all incoming transactions for compliance purposes, and deposits flagged as suspicious may be withheld for manual review", and in rare cases funds "may be returned to the sender address" [8]. The spot fee is 0% during beta with an explicit warning it may change afterward [5]. Contracts charge a fixed premium over daily FPPS (premium size not published) [5].

Proof & verifiability

The order book proves itself with data: a public API returning real matched orders (58 bids, 9 asks at check) [3]. The pool's payout rules are fully published, including the minimum on-chain payout and the free Lightning option [3]. The pool ranks eleventh on independent block data (14 blocks in a recent week) [11]. What is not published: the contracts' premium levels, the spot minimum bid, and any audit of delivered hashrate for contract buyers [5]. One unadjudicated community report of a pool login outage exists (single Reddit source) [12].

Reliability & history

The pool's lineage is the deepest in the industry - "1.3M+ BTC Mined since 2010" [3] with anniversary coverage of 1.31 million bitcoins mined [6]. BraiinsOS ships monthly releases [10], and the group added a commodity-capital arm and non-custodial loans [3]. A claimed Tether partnership does not exist - news searches return only false positives [12]. The corporate history is a two-layer structure: Czech operating entities (including a 9.5% CZK bond program) beside the BVI pool entity [1].

Pricing

Pool: 2.5% FPPS with daily payouts at 09:00 UTC; on-chain payouts free at 0.005 BTC and above, 0.0001 BTC below that; Lightning free from one satoshi; 0% pool fee with BraiinsOS (which charges a 2-2.5% dev fee instead) [2][9]. Hashpower: 0% spot fees during beta; contracts at a fixed premium over daily FPPS; minimums not published [4][5]. No ID-KYC anywhere - Telegram and email suffice - with deposit screening and possible withholding of flagged funds [8].

Verdict

Braiins is the most credible place to buy hashrate outright: the oldest pool, a genuinely live order book, and the clearest beta-period pricing on the market [3][4][5]. The honest caveats: the 0% beta fee is explicitly temporary [5], contracts price opaquely per deal [5], deposits face compliance screening without ID-KYC [8], and the legal entity sits offshore like its peers [1]. Start with small spot bids while the platform is in beta [4].

// How to get started with Braiins

Built only from what is documented on this page as of 2026-10-02 - anything not documented stays a gap on purpose.

1. Open the provider site

   Everything happens on braiins.com - we count the click, nothing else changes for you.

2. No ID check documented

   KYC is documented as none as of 2026-10-02. Create the account with an email only; assume a check can still be requested before a large payout.

3. Pick the smallest unit that still works

   Price from $8.33/pool 2.5% FPPS, minimum $8 - start with the minimum, not with the plan the checkout page pushes.

4. Pay

   Accepted: BTC. Check the network and the deposit address inside your account, never from an email.

5. Read the term before you sign

   62-day contract · maintenance Braiins Pool 2.5% (0% with Braiins OS); Hashpower spot bid fee 0% during Beta · refund: Hashpower: 14-day consumer withdrawal before delivery starts (full refund to paying address). A term you did not read is money you cannot get back.

6. Verify the output, not the dashboard

   Proof is documented as partial - Pool hashrate/payouts and the Hashpower order book are publicly observable, but Hashpower is explicitly in BETA and delivered hashrate is not…. Compare the first payout with the pool or wallet before scaling up.

7. Know the exit

   Payout frequency: Daily payouts created at 09:00 UTC. Threshold: Minimum payout 0.0002 BTC; free onchain payout at 0.005 BTC+; Lightning min 1 satoshi (free). Refunds: Hashpower: 14-day consumer withdrawal before delivery starts (full refund to paying address).

Then run the math: mining calculator · contract vs. HODL · all hashrate market providers.

What "legit" does not mean

A real, operating provider can still lose you money: with a contract you own no hardware, revenue follows coin price and difficulty, and most published contracts are priced so the seller comes out ahead. "Legit" means the operator exists and pays what its terms promise - not that the deal is profitable. 20 dated sources back this page; they are listed under sources.
