Buy a miner or rent hashrate?
You can own a small miner at home, or rent someone else’s for a while. Both are mostly a hobby and a lottery ticket, not an income. Renting skips the noise, heat and power bill; owning means you keep something at the end. Here’s the plain-English comparison, and how to avoid the scams that live next door.
Side by side
| Buy a home miner | Rent a miner or hashrate | |
|---|---|---|
| Upfront cost | A beginner miner costs a few hundred dollars (a Bitaxe Gamma is $139 at the lowest tracked price), plus a power supply if it isn't included. | Small. Physical rentals start from about £1 a day; hashrate marketplaces let you start with a small bitcoin deposit. |
| Noise and heat | A Bitaxe hums like a desk fan and gives off about as much heat as a phone charger; bigger miners are loud and hot. Welcome in a Melbourne winter, not in a Brisbane summer. | None in your home. The noise and heat are someone else’s problem. |
| Electricity | You pay Australian prices: about 28.2c/kWh on the Victorian default offer, so a Gamma costs around $44 a year to run. Solar helps while the sun is up. | Built into the price. You never see a power bill, but you pay for the power through the rental. |
| Solo odds | Your odds depend only on hashrate and time. A Gamma running all year has roughly a 1 in 16,800 chance of a block. | Exactly the same maths. Renting a big miner for a short time buys about the same odds as a small miner for longer. Renting doesn’t improve your luck per dollar. |
| Flexibility | You can tinker, change pools, sell the miner or stop at any time. Setup is yours to do. | Very flexible: pick a length, change your mind next month, try a bigger machine for a day. No setup or repairs. |
| At the end | You still own a miner with some resale value, and it keeps hashing. | You own nothing. When the rental ends, the hashrate stops. |
| Counterparty risk | Low: once it’s delivered, the miner is in your home and nobody else can switch it off. | You’re trusting the operator to run the hardware honestly and still be around tomorrow. Point it at a pool you choose so you can check the work yourself. |
A year of owning vs a year of renting
The same miner for the same 12 months: what it costs, what it would earn in a pool, and its chance of a solo block. Rental prices from WildWatts, checked 2 Nov 2026.
| Option | Cost for a year | Pool earnings / yr ? | Solo odds / yr ? |
|---|---|---|---|
| Own a Bitaxe Gamma 1.2 TH/s for a year | $183 $139 miner + $44 power | $21 | 1 in 16,800 |
| Rent a Bitaxe Gamma (WildWatts) 1.2 TH/s for a year | £182.50 (≈ $348) 365 days at £15 per 30 days | $21 | 1 in 16,800 |
| Own a NerdQaxe++ 4.8 TH/s for a year | $574 $399 miner + $175 power | $83 | 1 in 4,200 |
| Rent a NerdQAxe++ (WildWatts) 4.8 TH/s for a year | £365 (≈ $696) 365 days at £30 per 30 days | $83 | 1 in 4,200 |
How we modelled a year of renting: WildWatts sells sessions of up to 30 days, so we priced a year as 365 days at the 30-day rate (about 12 back-to-back 30-day sessions, with no gaps or downtime). Owning means the lowest tracked price for the miner plus a year’s power. Computed 3 Nov 2026, 1:03 am AEDT: difficulty 148.4 T, hashprice 42.6 sats/TH/day, BTC $111,160. Power at the Victorian default 28.2c/kWh, running 24/7. GBP converted at 1.91 (Frankfurter (European Central Bank reference rates), 2026-10-30). Today’s conditions, not a forecast. Over a year, the same miner earns the same and has the same odds whether you own it or rent it. Owning costs less in the first year and leaves you with a machine; renting spares you the noise, heat and setup. Either way the expected earnings are far below what you pay, so you’re paying for the fun and the lottery ticket.
How to spot a cloud-mining scam
“Cloud mining” sites that sell you a share of a far-away mining farm are one of the oldest crypto scams. Real mining income goes up and down with the bitcoin price, the difficulty and plain luck, so be very wary of any of these signs:
- Guaranteed daily returns. “Earn 3% a day” or a fixed payout every 24 hours. Mining can’t promise that. ASIC’s Moneysmart says guaranteed high returns are a typical scam tactic.
- Referral pyramids. Bonuses for signing up friends, “levels” or team commissions. Scamwatch warns about schemes that ask you to promote them to friends and family for commission.
- No verifiable hashrate or pool proof. If you can’t point the hashrate at a pool you choose and watch it arrive there, you’re trusting a dashboard the seller controls. HashFlare’s dashboard showed customers mining profits from falsified data, according to the US Department of Justice.
- Anonymous operators. No real company name, registration number or address you can check, or a domain registered a few weeks ago.
- Withdrawal minimums, lockups or extra fees. Small early withdrawals work, then you’re told to deposit more, pay a “tax” or wait out a lock-up period before you can get your money. ASIC lists “you need to pay more to access your money” as a red flag.
A real example. HashFlare sold more than US$577 million of cloud-mining contracts between 2015 and 2019 without the computing power to do most of the mining it claimed. Its two founders pleaded guilty to wire-fraud conspiracy in 2025 (US Department of Justice).

| Service | How it works | Cost | Watch out for |
|---|---|---|---|
| WildWatts Our pick UK · by The Solo Mining Co’ | Rent a real, physical miner (Bitaxe Gamma up to Avalon Q) on a rack at a UK solar-and-battery site for 1, 7, 14 or 30 days. You point it at any pool or solo server, so you can check the hashrate yourself, and you keep whatever it finds. | From £1 a day; Bitaxe Gamma £15 (≈ $29) for 30 days. Card, bitcoin or shop credit. | Small and new (launched 2026). Non-refundable once a session starts. |
| Braiins Hashpower Braiins Mining Limited, British Virgin Islands | A live marketplace for Bitcoin hashrate. You deposit bitcoin, then bid a price and budget and send the hashrate to your own pool. A “Try Your Luck” option points it at solo mining for you. | Spot-market fee 0% during the beta (may change). Solo tiles start around 10,000 sats. | Bitcoin only, and there are no withdrawals: deposits can only be spent on hashrate. Telegram needed for two-factor confirmation. Deposits are screened and can be held for review. Cheap bids can be outbid. |
| NiceHash Hashrate marketplace | A long-running marketplace where you buy hashrate from other people’s miners and point it at a pool you choose. Orders run until the budget is spent or you cancel. | 3% of the bitcoin spent on delivered hashrate, plus 0.00001 BTC per new order. Withdrawal fees apply. | Full identity check (KYC) before you can use it. It’s a trading tool more than a beginner product. About 4,700 BTC was stolen from it in a 2017 hack (NiceHash). |
| Contract “cloud mining” sites Fixed-term contracts with daily payouts | You buy a contract and the site credits you a payout each day from mining you can’t see. | Varies | Mostly not worth it You can’t check the hashrate, you rely on the seller’s dashboard, and if the business were profitable it would have little reason to sell you the profit. Many are outright scams (see above). |
We couldn’t find a published restriction on Australians using Braiins Hashpower or NiceHash, but both say it’s up to you to make sure the service is allowed where you live. Check at sign-up.
Why WildWatts is our pick
WildWatts rents you a specific, physical miner rather than a vague share of a farm, and you choose the pool. That one design choice removes the biggest cloud-mining problem: you can confirm the hashrate on your own pool’s dashboard instead of trusting theirs. The prices are published, short sessions are cheap, and there are free 24-hour sessions on some machines to try it out. It’s the honest version of “cloud mining” for a beginner who wants a go at solo mining without a fan humming in the lounge room.
Start with a free session or a single day before paying for a month. Treat anything you pay as spent, the same as a lottery ticket.

- Read is home mining worth it? for the honest maths on owning.
- Whichever way you go, send what you mine to a wallet you control: see hardware wallets.
