Bitcoin Gift for a Bitcoiner: Is a Bitaxe Solo Miner Worth Giving?

By Dominik Lederer, Founder, Hardware Engineer and Solo Mining Expert at Polarblocks. Network figures read from mempool.space on 12 October 2026 at 07:11 UTC, with the bitcoin price carrying its own timestamp of 07:05 UTC. Product details from the Polarblocks shop the same morning.

Picture the person on your list who already owns a hardware wallet, has read the white paper twice and will explain the halving to anyone who stands still long enough. A gift card feels like giving up. Another mug with an orange logo is worse.

A Bitaxe is the obvious answer, and I am not neutral about it: I build and sell the Bitaxe Gamma 601 at Polarblocks. So this article does what a shop page will not. It prices the gift for the person who receives it, puts it next to bitcoin itself and a lottery ticket, and says plainly where it loses.

What makes a Bitaxe a different kind of Bitcoin gift?

A Bitaxe is a Bitcoin gift that takes part instead of waiting. Plugged into an ordinary socket and pointed at the recipient's own Bitcoin address, a Bitaxe Gamma 601 joins the race for every new block around the clock at 15 to 19 watts. Bitcoin bought as a present only moves with the price.

Bitcoin adds a block about every ten minutes, which makes 52,560 rounds a year. That number is the protocol's target, not a measurement, but it is the right picture: 52,560 times a year the little machine on the shelf buys a ticket in the same draw as the industrial farms. If it wins, Solo CKPool, the pool Polarblocks recommends, writes the reward straight to the miner's own address in the block itself. Block 960,804 shows how: its first transaction pays two addresses, 98 percent to the miner and 2 percent to the pool.

The object matters as much as the odds. The Arctic Night edition arrives fully assembled and tested with a 25 watt power supply, a 3D printed stand and a 0.91 inch display that shows hashrate, temperature and status. The firmware and the circuit board are published on GitHub. The chip is not: the bitaxeGamma repository says of the BM1370, plainly, that it is not open source.

One drawback belongs in this paragraph, not in the small print. The standard Eco Line editions cool the chip with a stock 40 by 20 millimetre fan that runs all the time and can be heard. A recipient who wants a quieter miner should look further down at the options with a Noctua fan, which the shop describes as extremely quiet or whisper quiet.

What are the odds that a gifted Bitaxe finds a block?

On 12 October 2026 a Bitaxe Gamma 601 at 1.3 terahash per second had annual odds of about 1 in 13,904 of finding a block, based on the network difficulty published by mempool.space. Those odds hold until the next difficulty adjustment, due around 16 October 2026, which was projected that morning to make them slightly worse.

The calculation takes three steps, and anyone can repeat it. Multiply the difficulty by 2 to the power of 32 and divide by the miner's hashrate in hashes per second; that gives the mean search time in seconds. Divide by 31,536,000 seconds a year to turn it into years. The reciprocal of that is the annual chance. According to mempool.space the difficulty stood at 132,716,002,350,731 after a retarget of minus 0.03 percent on 3 October 2026 at 07:16:36 UTC, at block 969,696. For 1.3 terahash per second that is about 438.5 billion seconds, or 13,904 years, so 1 in 13,904 a year.

The 1.3 is our factory setting and a rounded figure. The bitaxeGamma repository derives about 1.2 terahash per second per chip for its reference design, which gives 1 in 15,062. Overclocked to 1.4, the odds improve to 1 in 12,911, at a higher power draw.

What is the prize worth? At 75,004 euros per bitcoin at 07:05 UTC on 12 October 2026, the 3.125 BTC reward alone came to about 234,388 euros before fees, a figure that moves with the exchange rate. Spread over 13,904 years, that is an expected value of 16.86 euros a year from the reward and 10 cents from the weekly mean of transaction fees, 16.96 euros in total before any pool fee and 16.62 euros after the 2 percent that Solo CKPool takes from the whole block.

The forces on that number pull in opposite directions, and not equally. Fees add those 10 cents. The retarget due at block 971,712 was projected at plus 5.28 percent at 07:11 UTC, with 653 blocks to go, which would cut the expected value by 5.28 divided by 105.28, about 5.0 percent or 85 cents, and stretch the odds to about 1 in 14,638. The projection moves by the hour.

What does a Bitaxe gift cost the person who receives it?

A Bitaxe gift hands the recipient an electricity bill. At 17 watts, the middle of the 15 to 19 watt band in Polarblocks product data, a Bitaxe Gamma 601 uses about 148.92 kilowatt hours a year: 52.12 euros at a house assumption of 0.35 euros per kilowatt hour, or 55.10 euros at the BDEW average of 37.0 cents.

That is about 4.34 euros a month at the house rate. The 0.35 euros is our own assumption and sits below the BDEW household average for Germany, which is why both figures stand side by side. The watt band matters too: 15 watts give 45.99 euros a year at the house rate, 19 watts give 58.25 euros.

Outside Germany, take the 148.92 kilowatt hours and multiply by the local tariff. The kilowatt hours travel; the euros do not.

Say it on the card. Few presents cost the person who unwraps them money every month, and a Bitaxe is one of them. The amount is small, but it comes every month the miner runs, so the recipient should know about the bill from the start.

Is a Bitaxe a better gift than bitcoin itself or a lottery ticket?

Not as money. 129 euros in bitcoin are worth that on the day, minus purchase fees, and LOTTO 6aus49 pays out half its stakes as prizes. On 12 October 2026 a Bitaxe expected 16.96 euros a year before pool fee: 9.4 percent of a 181.12 euro Snowstorm first year at 0.35 euros per kWh, 9.2 percent of 184.10 at 0.37.

The chart speaks against my own product in two places, so let me read it out. If the point of the present is money, give bitcoin. 129 euros bought 171,991 satoshis at the morning's price, before purchase fees, and they belong to the recipient the moment the transfer confirms. If the point is the expected payout per euro, a lottery comes out ahead: LOTTO 6aus49 pays out 50 percent of its stakes as prizes, less than half of what a player spends once processing fees are counted, against the Bitaxe's 9.4 percent of its first year, or 9.2 percent at 37.0 cents, before any pool fee. In a year without a device price the Bitaxe's share rises to 32.5 percent of its electricity, or 30.8 percent at 37.0 cents, before any pool fee, and only for as long as difficulty, bitcoin price and the 3.125 BTC subsidy stay where they stood on 12 October 2026.

Where the Bitaxe wins is the chance of a top prize per year and per euro of running cost, and the interest it holds. A line of LOTTO 6aus49 in every one of the 104 draws a year costs 124.80 euros in line fees alone and gives top tier odds of about 1 in 1,344,598 a year, from the published 1 in 139,838,160 per draw. The Bitaxe plays for a smaller prize, but at about 1 in 13,904 a year for 52.12 euros of electricity, or 55.10 euros at 37.0 cents. And a lottery ticket is finished minutes after the draw. A Bitaxe sits on a shelf and keeps an all-time best difficulty in its dashboard that only climbs, more and more rarely, unless the firmware memory is wiped. That record is a near miss counter, nothing more, but it gives the recipient something to check. A lottery line does win small prizes far more often than a Bitaxe finds a block; the Bitaxe has no small prizes at all.

What does the recipient need before switching it on?

The recipient needs three things: a 2.4 gigahertz Wi-Fi network, a Bitcoin address they control, and a solo pool to point the miner at. Polarblocks product data for the Eco Line promise Wi-Fi setup in under five minutes, and the setup guide recommends Solo CKPool at eusolo.ckpool.org.

The Wi-Fi point needs checking before wrapping. The Bitaxe Gamma design uses an ESP32-S3 module, and Espressif lists 2.4 gigahertz Wi-Fi, 802.11 b/g/n, for that chip, with no 5 gigahertz band. Whatever the router does with its 5 gigahertz band, its 2.4 gigahertz band has to be switched on.

The setup follows the shop's own guide. Connect a phone to the miner's access point via the QR code on the display or the phone's Wi-Fi list. Join the home network in the page that opens. Type the local IP address shown on the display into a browser to reach the AxeOS dashboard. Enter the pool and the Bitcoin address under "Pool", save, and the miner restarts and starts mining.

The address deserves a moment of thought before wrapping. It has to belong to the recipient, not to the giver, because whoever controls that address controls a block if one is ever found. Leave the address step for the unwrapping. Setting it up together is half the present, and the recipient learns where a block reward would land and why no exchange account sits in between. Our longer piece on solo mining versus pool mining explains what the pool does and does not get to keep.

Which Bitaxe edition suits which recipient?

For a first gift, the 129 euro Snowstorm edition, currently reduced from 149 euros, or the all black Arctic Night at 149 euros make the most sense. For a recipient who cares about a cause, the Greenland edition at 199 or 219 euros donates 5 euros per miner to Transparency International Greenland. All three run at 1.3 terahash per second.

That last sentence is the honest core of the choice. Paying more does not buy better odds. Every edition above carries the same BM1370 chip at the same factory setting, so every one of them has the same 1 in 13,904 a year. What changes is the look, the cooling and the bill.

The Greenland edition uses a Noctua NF-A4x20 PWM fan, optionally two, and comes with a 30 watt power supply. Its product page states about 19 watts, which puts electricity at 166.44 kilowatt hours, 58.25 euros at the house rate or 61.58 euros at 37.0 cents. Its first year with one fan comes to 257.25 euros, and the expected value of 16.96 euros covers 6.6 percent of it. The buyer is someone who wants the Noctua fan and the donation, not a better lottery. A cheaper route to a Noctua fan is the Silent Night bundle, 139 euros in white, currently reduced from 159, or 159 euros in black, built around an Eco Line Gamma at about 19 watts and the same factory setting of 1.3 terahash per second according to its product page, so with the same 1 in 13,904.

Two smaller options round it out. The NMminer TV at 25 euros is a small ESP32 based miner with a 1.54 inch colour display that mines at up to 1,060 kilohashes per second on about 0.8 to 1 watt. Its annual odds are about 1 in 17 billion at best, so it is a desk ornament that explains mining, not a lottery ticket. And for a Bitcoiner who already owns a Bitaxe, the 9 euro Polar Night stand is the cheapest present on this page.

Any plan that looks further than one year needs two caveats. Difficulty is adjusted every 2,016 blocks, about every two weeks, and each rise lowers the odds and the expected value. The halving expected in the first half of 2028, about 78,941 blocks from now, cuts the prize to 1.5625 BTC plus transaction fees. It halves the block subsidy, not the chance of winning, while the electricity bill stays where it is.

If you want to give a Bitcoiner money, give them bitcoin. A Bitaxe is a different present: a ticket in the same draw as the industrial farms, on their own desk, paid for by their own electricity. Tell them the odds and the bill on the card.

Frequently asked questions

Is a Bitaxe a good gift for a Bitcoiner?
A Bitaxe Gamma 601 is a good gift for a Bitcoiner who wants to take part in the network and learn how mining works, and a poor one as money. On 12 October 2026 its expected value was 16.96 euros a year before any pool fee, 9.4 percent of a 181.12 euro first year with the 129 euro Snowstorm edition at a house assumption of 0.35 euros per kilowatt hour, or 9.2 percent of 184.10 euros at the BDEW average of 37.0 cents, and 32.5 percent of its electricity at 0.35 euros, or 30.8 percent at 37.0 cents, against annual odds of about 1 in 13,904 of a full block.

How much electricity does a gifted Bitaxe use?
A Bitaxe Gamma 601 at 17 watts, the middle of its 15 to 19 watt band, uses about 148.92 kilowatt hours a year, which is about 52.12 euros at a Polarblocks house assumption of 0.35 euros per kilowatt hour or 55.10 euros at the BDEW German average of 37.0 cents. The recipient pays it.

What does someone need to set up a Bitaxe they received as a gift?
They need a 2.4 gigahertz Wi-Fi network, a Bitcoin address they control and a solo pool such as Solo CKPool. Polarblocks product data put Wi-Fi setup at under five minutes: connect to the miner's access point, join the home network, open the AxeOS dashboard and enter the pool and the address.

Does a more expensive Bitaxe edition have better odds?
No. The Snowstorm and Arctic Night editions of the Bitaxe Gamma 601 and the 199 or 219 euro Greenland charity edition from Polarblocks all carry the BM1370 chip at a factory setting of 1.3 terahash per second, so all had annual odds of about 1 in 13,904 on 12 October 2026. A higher price buys cooling, looks or a donation.
