Cloud mining is a simple product with an unforgiving business model. You rent a slice of somebody else's hashrate for a fixed period, they pay you the coins minus a maintenance fee, and you never see the hardware. In 2026, at current hashprice, that maintenance fee is usually larger than the coins. This is the honest version of how it works and why the maths keeps going the wrong way.

Written for buyers considering a contract with BitDeer, BitFuFu, ECOS or one of the smaller providers, and for anyone who has already read the marketing and wants an independent view before paying. If you already know cloud mining isn't for you, the hosted vs cloud comparison is the shorter version and the profitability ranking shows what real machines earn instead.

Four mining models, one page

  • Solo mining — you run a rig against your own full node. Full block reward if you win a block; you almost never will unless you own petahashes.
  • Pool mining — you run a rig, point it at a pool (Foundry, ViaBTC, Braiins), share rewards proportionally, pool fee 1–2%. This is what serious miners do.
  • Hosted mining — you buy the physical ASIC, ship it to a colocation facility, they bill electricity plus a small rack fee, you keep 100% of the coins. You own an asset with residual value.
  • Cloud mining — you buy hashrate you never see. The provider pays you a daily amount in BTC and deducts a daily maintenance fee. When maintenance exceeds payout, the contract stops.

All four are legal in most jurisdictions. Only cloud mining puts you on the wrong side of the maintenance-fee curve by design.

What a 2026 cloud contract actually looks like

Every serious cloud provider prices the same way, whether they say so plainly or bury it in the terms.

  • Contract length — usually 6, 12, 24 or 36 months. Some legacy providers still sell "lifetime" contracts, which is a way of saying "until the fee exceeds the payout".
  • Upfront cost — a one-off charge per TH/s or PH/s of hashrate rented.
  • Daily maintenance fee — a fixed $/TH/day charged against your payout. This is the number to check.
  • Auto-shutdown clause — the contract terminates when maintenance exceeds the daily payout for a certain number of consecutive days.

BitDeer, currently the largest listed cloud mining operator, splits its pricing into a hashrate fee and an electricity fee — roughly $0.0029–0.0033 per TH per day for hashrate and about $0.053 per TH per day for electricity. That is roughly $56 per PH/day in fees before you receive a single satoshi. At an August 2026 hashprice of about $32.10 per PH/day per Hashrate Index, the maths does not work.

The maintenance fee always wins in the end

Cloud mining looks profitable in the month you buy it. It becomes unprofitable the moment the network difficulty adjusts upward or the coin price drops, because your hashrate produces fewer coins but the maintenance fee stays fixed.

Hashprice — the daily USD revenue per PH of Bitcoin hashrate — is the number that decides. In 2026 it has moved between roughly $27.70 (June low) and $37.60 (January) per PH/day, per Hashrate Index. Cloud contracts priced against the January number were negative by June. Every difficulty adjustment (~ every two weeks) chips away at your side of the balance.

A worked example on an S21 XP hashrate equivalent (about 216 TH/s):

HashpriceGross dailyCloud fees (est.)Net (cloud)Net (own machine, hosted at $0.014/kWh)
$37/PH/day$7.99$12.10−$4.11+$6.81
$32/PH/day$6.93$12.10−$5.17+$5.75
$28/PH/day$6.05$12.10−$6.05+$4.87

Contract fees are indicative — providers vary — but the shape is the point. Cloud contracts are structurally negative once hashprice normalises. An owned machine at industrial hosted power stays positive across the same range.

The historical record on cloud providers

The industry's short history is a series of cautionary tales:

  • HashFlare — Estonian, $577M gross. Founders pled guilty in February 2025; the DoJ established that HashFlare ran under 1% of the hashrate it claimed and the customer dashboard was fabricated.
  • BitClub Network — $722M, indicted in 2019. MLM structure, fake mining dashboards, five defendants charged; the case is still being litigated.
  • Genesis Mining — legitimate operator that shut open-ended Bitcoin contracts in 2018 when payouts dropped below maintenance fees. Not a scam, but a demonstration of the maintenance-fee trap in action.
  • MiningMax, HashOcean, PBmining, Power Mining Pool — earlier exit scams, no meaningful recoveries.

Genesis is the important one. Their contracts were honest and their fleet was real. They still had to cancel because the maths crossed the wrong way. If the honest ones can't stay profitable, the marketing-heavy ones certainly can't.

Providers that at least exist in 2026

A short list of currently-active operators, without endorsement:

  • BitDeer (Nasdaq: BTDR) — publicly listed, publishes monthly production figures, hardware exists. Contract terms are visible and honest. The maths is still against the buyer.
  • BitFuFu (Nasdaq: FUFU) — publicly listed, Bitmain-affiliated. Same shape as BitDeer.
  • ECOS — Armenia FEZ, licensed. Contracts $150 upwards, terms clearly stated.
  • StormGain Cloud Miner — a promotional in-app product paying a few sats an hour. Not a serious mining operation and not marketed in the UK.
  • Compass Mining — often mis-listed as cloud. It is a hosted mining provider, not cloud.

If you buy from any of these, read the fee schedule and the auto-shutdown clause first. Everyone else — the ads on TikTok, the "guaranteed 1% daily" sites, the referral-heavy telegram groups — is not on this list for good reason.

UK and EU regulation is now serious

Since 8 October 2023, every crypto financial promotion in the UK must be approved by an FCA-authorised firm, with a mandatory risk warning and a 24-hour cooling-off period. The FCA has issued over 450 alerts against unauthorised operators since; specific cloud mining names — Cloud Mining City, Crypto Mining Limited, CoinCloud Mining Platform — are on the FCA warning list.

Under MiCA, in force in the EU from December 2024 with the full CASP regime by mid-2026, cloud mining contracts marketed with fixed daily returns are treated as collective investment schemes or securities. Most offshore cloud operators have not sought authorisation, so promoting them into the EU is unlawful.

Practically: if a cloud mining ad is targeting UK or EU residents in 2026 without a visible FCA statement or MiCA authorisation, the promotion itself is likely illegal, regardless of whether the underlying business is a scam or an honest operator.

Hosted mining is the model that actually works

The alternative most cloud-mining searchers actually want: own the ASIC, pay only for electricity, keep 100% of the coins. The economics reverse the incentive — the operator makes money on power markup, not on your payout shrinking.

Concretely: a Bitmain Antminer S21 (200–235 Th/s, 17.5 J/TH) hosted at our $0.014/kWh Bhutan rate runs about $1.18/day in electricity and grosses $6–$8 in coins at current hashprice. Net is $4.80–$6.80 daily, which is the mirror image of a cloud contract. And you own the machine — a depreciating but real asset with resale value.

Compare across other coins:

  • Bitmain KS5 Pro for Kaspa (21 Th/s, 3,150 W) — around $8–$14/day at Kaspa's current network position, hosted.
  • Bitmain Antminer L9 for Doge/Litecoin merged mining — $4–$6/day at hosted power.
  • Antminer S23 Hyd for buyers with capital wanting the current efficiency leader — $12–$18/day.

Live numbers on all of them are on the 2026 profitability ranking.

When cloud mining does make sense

Three narrow scenarios:

  • You want tiny exposure for education. Buy a small BitDeer or ECOS contract, watch the daily arithmetic, learn how hashprice affects payouts. Treat the cost as tuition.
  • You are extremely bullish on BTC over the contract period. If BTC doubles and difficulty doesn't, cloud contracts pay because coin-denominated payouts stay constant while their USD value rises. This is a leveraged bet on price, not on mining.
  • You genuinely cannot host or own hardware. Renters with no outbuilding, no willingness to arrange a facility contract, and small capital. Even here, spot BTC or a Bitcoin ETF is usually the better trade.

Every other case, the arithmetic favours owning a real machine.

FAQ

What is the difference between cloud mining and hosted mining?

Cloud mining rents you a share of hashrate you never see. Hosted mining puts a physical ASIC that you own into a colocation facility. In cloud, the operator is incentivised to shrink your payout to protect their margin. In hosted, they profit from electricity markup and you keep 100% of the coins.

Is cloud mining profitable in 2026?

Rarely. Every published fee schedule from a legitimate cloud operator lands at or above current hashprice once electricity and maintenance are combined. Contracts priced at the top of the hashprice cycle are usually underwater by the following quarter.

Which cloud mining companies are legitimate?

The publicly-listed operators BitDeer and BitFuFu are real businesses with real fleets. ECOS is a licensed Armenian operator. Everyone else on the TikTok ad wave is either unlicensed, actively fraudulent, or both.

Why do cloud mining contracts end early?

Every serious contract has an auto-shutdown clause: when the daily maintenance fee exceeds the daily payout for a set number of consecutive days, the contract terminates. That happens routinely when hashprice drops or network difficulty adjusts upward. Genesis Mining shut open-ended Bitcoin contracts in 2018 for exactly this reason.

Is cloud mining legal in the UK?

Selling and buying it, yes. Promoting it to UK residents without FCA-approved financial promotion status is a criminal offence under FSMA. Most cloud mining ads targeting UK residents are technically illegal even if the underlying operator is honest.

Can I mine Bitcoin without buying hardware?

Only through cloud mining or by renting hashrate on a marketplace like NiceHash. Both produce worse economics than owning a machine and hosting it at industrial power. Buying spot BTC is usually a better trade than renting hashrate.

What is hashprice and why does it matter for cloud contracts?

Hashprice is the daily USD revenue per unit of Bitcoin hashrate. It moves with coin price, network difficulty and transaction fees. Cloud contracts have a fixed fee against a floating hashprice, which is why they turn negative when hashprice drops.

How do I know if a cloud mining site is a scam?

Guaranteed daily percentage returns, referral commissions across multiple levels, no visible facility, "lifetime" contract wording, withdrawals paused for "system upgrades", payments only in the platform's own token, and a domain less than 12 months old. Any two of those and the answer is no.

Skip cloud mining. Own the machine and keep the coins.

Buy a real ASIC from us, host it at $0.014/kWh in one of our facilities, keep 100% of the coins it mines. No contracts, no maintenance fees, no auto-shutdown clauses.
