Frequently asked questions

They can. A miner earns coins for the work it does on a blockchain, and you keep what is left after paying for electricity. Whether that is a profit depends mostly on three things: how efficient the machine is, what you pay for power, and the coin's price and difficulty, which change every day.

Every miner page on MinerPrices shows today's revenue, electricity cost and profit at the electricity price you set at the top of the page.

Yes. Buying a machine, plugging it in and pointing it at a mining pool takes an afternoon. Treat it as a high-risk investment though: income is not guaranteed and coin prices swing hard. Our Dictionary explains the terms you will meet in plain English.

Most ASIC miners use as much power as a few kettles running all day, give off a lot of heat and are very loud (often 70 to 80 dB). You need suitable wiring, ventilation and a place where the noise does not matter. If that is a problem, hosting puts your machines in a facility built for them, and our hosting vs own site calculator compares the costs.

Pools pay into a wallet address you choose. For anything you plan to hold, use a wallet where you control the keys, ideally a hardware wallet such as Trezor or Ledger, and avoid leaving large balances on an exchange or in a pool account.

Send them to a regulated exchange that serves your country, such as Coinbase, Kraken or Binance, sell them there and withdraw to your bank. Compare fees and check which coins each one supports. Taxes on mining income differ by country, so keep records of what you mine and sell.

For every miner we take live network data (difficulty, block reward, coin price), updated every 15 minutes, and work out what its hashrate earns per day. We subtract the electricity it uses at your price per kWh.

Each machine is rated on the coin that earns the most money on its algorithm. Coins that are mined together, like Litecoin and Dogecoin, are counted together.

Yes. The bar at the top of every page has the currency (USD, EUR, GBP, CZK and more) and your electricity price per kWh. Both apply across the whole site, including every calculator, and your browser remembers them for next time.

Because they are live. Difficulty, block rewards, coin prices and exchange rates move all the time, and we refresh them every 15 minutes, so the same machine can earn a little more or less an hour later.

On miner pages, ROI is the number of days a machine needs to pay for itself from its daily profit: the offer's price divided by profit per day, at your electricity price and today's network conditions. Each offer shows its own ROI; the headline uses the best price. For a pre-order, add the time until delivery.

It is a snapshot, not a forecast. The ROI calculator lets you add rising difficulty, coin price changes and the next halving for a more realistic estimate.

Sellers with the Verified seller badge have been checked by us: their identity and company registration were reviewed and screened against U.S. sanctions lists. That tells you a real company stands behind the listing. It is not a guarantee of every order, so still compare prices, read the terms and pay safely. Our scam warning signs help you spot a bad offer.

No. We compare machines and list offers from sellers and hosting providers. When you click an offer you buy directly from that seller, on their terms; we are not part of the sale and never take payment for hardware.

Each seller sets their own options. Common ones are bank transfer (often in USD), cryptocurrency (very common) and, less often, card or PayPal. Pre-orders usually need a deposit. Paying the full amount in crypto up front to a seller you do not know is the riskiest option.

In stock machines ship now and start earning sooner. Pre-orders ship from a future production batch, usually cheaper per TH but with the risk that prices or difficulty move before delivery. Miner pages show each offer with its delivery date so you can compare.

We are a team of engineers based in Prague, Czechia. We originally developed this tool to help ourselves select and compare ASIC miners before making a purchase. Realizing its value, we decided to make it publicly available and build a community where users can share useful opportunities rather than keeping the knowledge to ourselves.

Many in the mining community have experienced scams and financial losses, and we aim to minimize this risk by sharing accurate and reliable information. We believe that the future of cryptocurrency should be safe and accessible for everyone.
