Mining: $2.78/day on an RTX 4090 (Pearl).
First payout within a day.
Mining around the clock, before electricity: $177 a month, the way most comparison sites count it.

Set it up once. It works while you rest.
Otium tests your hardware, picks the coin that pays your card the most, and switches as prices change. You don't touch it again.

Choose where to be paid
Pick a coin and paste your wallet address. The default is USDT on TRON, which is worth a dollar and pays out from 1.5 USDT.
Walk away
A few minutes after you leave the keyboard, your processor and graphics card start mining. Touch the mouse and they stop within a second.
The pool pays you
unMineable sends your earnings straight to your address once a day after the minimum. Otium never holds your money and can't touch it. How payouts work
Pearl mining runs the math AI runs on.
Most coins burn power on hashes nobody needs. Pearl is a proof-of-useful-work coin: mining a block means multiplying large matrices, the same operation every AI model is built from, and its protocol is designed so that work can be real AI computation, such as serving a language model. That's why NVIDIA cards with tensor cores mine it best, and why it pays more than any other coin a gaming card can mine today.
Through a pool, your card multiplies the matrices the network hands it. It doesn't run anyone's AI model or see their data. What is Pearl?
It watches the price of power by the hour.
When electricity would cost more than mining earns, Otium waits. In Norway, Sweden, Denmark and Finland it follows the live hourly price for your area, so it mines through the cheap night hours and sits out the evening peak.
Electricity included in your rent, or paid by someone else? Say so when you set it up, and Otium earns whenever you're away.

$96.25of every $100 your processor mines stays yours. The rest goes to the mining software (1%), the pool (0.75%) and Otium (2% of mining time).

Otium's 2% is how it pays its way, with no ads and no data sold: the servers, payouts to your own wallet, and development and support. What that covers
What comes off, and who gets it
- Otium
- 2% of mining time, about 29 minutes per day of mining, mined to Otium's own address. Nothing while Otium is paused, and nothing during fee-free days. It pays for Otium's servers, for setting up payouts to your own wallet, and for development and support.
- Mining software
- XMRig keeps 1% (processor); SRBMiner keeps 0.85%–2% (graphics card, depending on the coin).
- Pool
- unMineable keeps 0.75% (1% without Otium's referral code).
- In total
- about 3.75% on the processor and 3.6%–4.75% on the graphics card.
- Also
- unMineable pays Otium 0.25–0.5% of what you mine there, out of its own fee. It doesn't come out of your earnings: Otium's referral code is what lowers your pool fee from 1% to 0.75%.
The pool pays your wallet. Otium never holds your money.
Mining and internet sharing each pay your own address, in the coin you chose. This is the path the money takes.
Mining
- Your computer mines on unMineable, under your address. Your processor mines Monero and your graphics card the coin that pays it most.
- unMineable converts it into your coin. A few hours after the mining, it adds the value to your balance at the pool, in USDT, BTC or whichever coin you picked.
- Once a day it pays your wallet, when your balance has passed the pool's minimum (1.5 USDT for USDT on TRON). Otium shows how close you are.
Check that "Auto pay" is on for your address at unMineable: new TRON addresses start with it off, and Otium warns you if it is. A balance with no mining for 6 months is lost at unMineable, so collect it if you stop. In the US, MoneroOcean pays Monero instead, from 0.003 XMR.
Internet sharing
- Proxybase pays for the bandwidth its buyers use, in dollars, into a small wallet Otium keeps on your computer.
- From $1, Otium has it converted and sent to your address in your coin. It waits while network fees would take more than 5% of the payout, so USDT on TRON arrives in payouts of about $16, and pays anyway from $25.
- The conversion goes through Relay (and SideShift for Litecoin, ChangeNOW for Monero). One that fails comes back to the wallet on your computer.
Otium's 2% of sharing earnings comes off; the rest reaches your address. Payouts only ever go to the address you registered, never anywhere the app or anyone else asks.
Mysterium and AIOZ skip the conversion. Mysterium pays MYST on Polygon straight to your address from 5 MYST, and Otium takes nothing from it. Otium sends AIOZ to your 0x address from 5 AIOZ; its 2% of what the node earns goes to Otium's address separately.
Bring a friend, and you both get 30 days without Otium's fee.
Then, for 6 months, 25% of Otium's fee on their mining is mined straight to your address.
Your fee-free days start once your friend has mined for a day (up to 90 days at a time). Friends on your own internet connection don't count.
Before you install
Is my money safe?
Otium never touches it. The pool pays your wallet directly, and you can check your balance on the pool's own page at any time.
Why does Otium take 2%?
It's how Otium pays its way, without ads or selling anyone's data. It pays for the servers behind the website, your account and invites, the update feed, and the price check that picks the best-paying coin for your graphics card every 10 minutes. It pays for setting up payouts to your own wallet: each miner set up for your coin and address, a check that the pool will actually pay you, and turning internet sharing's earnings into your coin. And it pays for development and support: keeping up as coins and pools change, signed updates, and help on Discord and by email. The fee is 2% of mining time, so you can see it happen, and it stops during fee-free days.
When do I get paid?
Mining: unMineable pays your address once a day after your balance passes its minimum (1.5 USDT for USDT on TRON, usually within a day or two of mining with a gaming graphics card). Internet sharing through Proxybase: from $1, once the network fees are a small part of the payout. Mysterium and AIOZ pay their own tokens from 5 MYST or 5 AIOZ. All of it goes straight to your own wallet. How payouts work
Is Otium open source?
Yes. The app and the server behind otium.lol are free software under the AGPL-3.0, and the code is on GitHub, so anyone can check what Otium does on your computer. Every update is signed with a key that never leaves the developer's PC. Questions? Join our Discord.
Why does my antivirus warn about it?
Antivirus tools flag every mining program, because criminals hide miners on other people's computers. Otium downloads the official open-source XMRig and SRBMiner releases, checks their fingerprints, and keeps them in one folder you can allow. It only mines when you've set it up and turned it on. How to allow it in your antivirus
Will it slow my computer down?
By default it only runs while you're away, and stops within a second when you're back. If you let it run while you work, it uses the lowest priority and only as much of the processor as you allow. Games and work always come first.
I live in the United States
unMineable doesn't serve US residents, so Otium pays you in Monero through MoneroOcean instead.
What about AMD graphics cards?
Otium tests Pearl on yours too: the mining software now runs it on recent AMD cards (an RX 9070 XT makes about $2 a day before power). If the pool doesn't accept an AMD card's work, Otium moves it to the next coin that pays your wallet more than the power it uses. Either way it's paid to your one wallet, and your processor earns too.
Which download do I need?
The Download button picks the installer for the computer you're on. To choose one yourself: Windows, Mac with Apple silicon, Mac with Intel or Linux (AppImage). The Mac and Linux versions are a beta in this first release: they work, but have been tested less than Windows.
Something isn't working
In Otium, open Advanced and press "Send a problem report". It sends what Otium knows about why it isn't earning, without your payout address or any keys, and gives you a reference. Then ask for help and mention it.
Will my computer go to sleep?
Not while it's earning: Otium keeps it awake so it can mine through the night, and the screen still turns off. When it stops earning (you're back, power is too expensive, or a laptop runs on battery) your usual sleep settings apply again. You can switch this off in Settings.
