Looking at OpenSourceMiners? A question we hear.
Is OpenSourceMiners' rental legit?
It looks like a real service. Open Source Miners is a shop for open-source Bitcoin miners such as the Bitaxe and NerdQaxe, run by Nanohash OÜ in Tallinn, Estonia, and listed as a verified Bitaxe seller. The company is registered in the Estonian business register, has filed its VAT returns and has no tax debts. Its rentals mine solo on its own public pool, pool.opensourceminers.de, with 0% pool fee, and a found block pays the full reward to your own address. You can look up your address on the pool to see booked and delivered hashrate.
It is also very new. Nanohash OÜ was registered on 23 February 2026 with €1 of share capital, has one owner and no employees reported, and hasn't filed an annual report yet. Its site names no team, and we found no list of blocks its renters have found, so you have less to check than with an older company.

Everything else, side by side.
The short version.
Every number here comes from the calculator and tables above.
Which one should I pick?
If you want the best chance for your money, pick the option at the top of the calculator. For most budgets that's a Power Mining 24-hour rental: it puts your whole budget into one day of hashrate at the lowest price per TH/s.
If you'd rather mine every day for months, compare "1 year". Power Mining rents virtual miners for a full year, from a small start fee; OpenSourceMiners rents for 1 month at most, so a year there means renewing every month at a higher price per TH/s. If you want to mine Bitcoin Cash, only Power Mining offers it.
How are the chances calculated?
The network finds about 144 blocks a day. Your share of them is your hashrate divided by the whole network's hashrate, times the number of days you mine. We use today's network hashrate: 1,062 EH/s for Bitcoin and 3.71 EH/s for Bitcoin Cash.
What does "1 in 1,500" mean?
If 1,500 people each bought that option, on average one of them would find a block. A smaller number is a better chance. Solo mining is a lottery: most rentals find no block, and nothing is guaranteed.
Is OpenSourceMiners' hashrate the same kind of hashrate?
Yes. Both sell SHA-256 hashrate from ASIC miners, pointed at your own address on a solo pool, so TH/s on one site equals TH/s on the other. OpenSourceMiners names its rentals after home miners (a "virtual NerdOctaxe Hydro" is 14 TH/s), but the hashrate comes from several sources, as it does at Power Mining.
Which prices did you use?
Power Mining: today's 24-hour rentals and 1-year virtual miners at the pay-for-12-months price, in US dollars without VAT. OpenSourceMiners, as listed on 2 November 2026: its four virtual miners and its custom hashrate (1.3 to 100 TH/s) for 1 day, 3 days, 7 days and 1 month, from its German page. OpenSourceMiners shows euros including 19% German VAT, so we took the VAT out and converted at €1 = $1.12 to compare both before tax. Its longest rental is 1 month, so for 1 year we count 12 monthly rentals at today's price. For custom amounts between the ones its page shows, we draw a straight line between the neighbouring prices.
Taxes may be added at checkout depending on your country. Prices change; check each site before you order.
Can I mine Bitcoin Cash at OpenSourceMiners?
No. Its rentals mine Bitcoin only. At Power Mining you can point a rental at Bitcoin Cash, whose network is about 300 times smaller, so the same hashrate gets about that many more chances. The prize is smaller too: 3.125 BCH instead of 3.125 BTC.
Can I repeat a 24-hour rental?
Yes. Choose "Repeat weekly" at checkout: you get one 24-hour rental every 7 days at the same budget, and 7.5% extra hashrate from week 2. Cancel anytime.
Ready for your shot at a block?
24-hour rentals from $10.42, no week-long commitment, or a virtual miner that mines every day. Bitcoin or Bitcoin Cash, 0% pool fee on Bitcoin, and blocks pay straight to your wallet.
