Overview
CudoMiner is not a cloud-mining seller: it is free desktop mining software (CudoMiner, CudoFarm, CudoOS) that runs on your own GPUs and takes a commission on output [1]. It is operated by CudoMiner Ltd, a British Virgin Islands company [2]. We list it under watch because the product has been visibly frozen since 2022 while the group behind it moved to enterprise AI compute [3][5].
What you can rent
Nothing is rented - that is the point to understand before reading further. You download the miner, point it at your own PCs, rigs or farm, and Cudo manages coin-switching, tuning and auto-exchange for a cut of what you mine [1]. There is no hashrate purchase, no contract term and no ASIC hosting [1]. If you were looking for rented hashrate, this category is the wrong one; our mining calculator assumes you own the hardware.
Contract & terms
There is no contract term and no minimum purchase: the terms are stop-and-start whenever you want, commission-only, with no subscription and no withdrawal fee [1]. Payouts go to a cryptocurrency of your choice, and for coins other than Bitcoin the amount is calculated using the BTC exchange rate on the day of mining [1]. A payout schedule (daily, weekly, threshold) is not published on the pages we could verify. KYC requirements are likewise not documented; a console account is required to run the fleet. The services are legally provided by CudoMiner Ltd, C/O Vistra (BVI) Limited, in Tortola - an offshore services address, not an operating office [2].
Proof & verifiability
Because mining runs on your own hardware, you can watch your local hashrate and pool-side shares directly - that part needs no trust. What cannot be verified are the platform's own claims: the "over 100,000 users" figure is marketing [4], and there is no audit, attestation or third-party verification of the platform's profitability claims or its backend health [1][3]. Your main counterparty exposure is the mined balance sitting in the console before withdrawal.
Reliability & history
No fraud, insolvency or exit incident involving Cudo itself was found. The warning sign is abandonment: the public changelog's newest entry is "Update Miners (15/04/2022)" [3], the site blog is frozen, and the parent group's energy now goes into CUDO Compute, an enterprise NVIDIA-GPU/AI infrastructure business [5]. The UK parent, Cudo Ventures Ltd (company 11065412, incorporated 15 November 2017), is still Active at Companies House but carries an "Accounts overdue" warning [6]. Separately, a February 2025 Reddit thread reports scammers impersonating a "Cudo miner developer" who promised to boost mining for a fee - third-party fraud, not a Cudo product fault, but expect it because the brand is well known [7][8].
Pricing
Software licence: free [1]. Commission on 30-day mined volume: 6.5% below 0.005 BTC, then 5% at 0.005, 4% at 0.01, 3% at 0.05, 2.5% at 0.1, 2% at 1, and 1.5% at 10 BTC or more; there is no withdrawal fee [1]. For payouts in coins other than Bitcoin, the fee is calculated using the BTC exchange rate on the day of mining [1]. There is no subscription and no commitment - you can stop and start devices whenever you want [1]. Because you mine on your own hardware, profitability depends entirely on your electricity cost and GPU efficiency, not on Cudo.
Verdict
Cudo is not a scam and never was - it is free software with unusually fair commission pricing, and your coins are mined on hardware you control. We keep it on watch, not because money is at unusual risk, but because the product looks unmaintained since 2022 [3] and the company has visibly moved on [5]: expect stale documentation, and treat any "Cudo developer" who contacts you as a scammer [7]. For pure rental income, compare actual cloud or hosting providers instead.
++ What works
- Named legal entities (CudoMiner Ltd BVI 2086929; Cudo Ventures Ltd UK 11065412)
- Free software with transparent, published commission tiers and no withdrawal fee
- No lock-in: stop and start devices anytime, no commitment
- Cross-platform GPU mining with management console (CudoMiner/CudoFarm/CudoOS)
- No Cudo-specific customer-loss or exit-scam incident found
-- What to watch
- Software release history ends 2022-04; blog/news content ends 2020 (effectively unmaintained)
- Parent company has pivoted to CUDO Compute (enterprise AI/GPU infrastructure)
- No audit, proof-of-hashrate or third-party verification
- Performance and user-count claims are marketing only
- Not an ASIC host, colocation or hashrate market - poor fit for buyers seeking hosting/market exposure
- Website now sits behind a Vercel bot challenge that blocks plain HTTP fetches

- Pay
Accepted: BTC. Check the network and the deposit address inside your account, never from an email.
- Read the term before you sign
maintenance None; commission-only (1.5-6.5% of mined value) · refund: No subscription/prepayment, so no refund mechanism is needed; commission is taken from mined output. A term you did not read is money you cannot get back.
- Verify the output, not the dashboard
No independent proof is documented. Withdraw the first payout early and compare it with the pool worker or your own wallet.

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. 12 dated sources back this page; they are listed under sources.
