Bitcoin lottery mining: the complete guide

How Bitcoin mining works in one page

Bitcoin transactions are grouped into blocks, and a new block is added about every ten minutes, around 144 a day. To add a block, a miner must find a number that makes the block's hash fall below a target set by the network. There is no shortcut: miners try trillions of guesses per second. Each guess is a hash. The miner who finds a valid one first broadcasts the block and receives the block subsidy, currently 3.125 BTC since the April 2024 halving, plus the transaction fees in the block.

The difficulty of the target adjusts every 2,016 blocks (about two weeks) so that blocks keep arriving roughly every ten minutes whatever the total hashrate is. As more hashing power joins, the target gets harder. So your share of the total hashing power is your share of the blocks.

Why solo mining is a lottery

Mining at a pool means many miners combine their hashing power and share each block reward in proportion to the work they contributed. You earn small, frequent payments. Solo mining means you keep the whole reward if you find a block, but you get nothing otherwise. Each hash is like a ticket in a draw with unimaginably small odds, so it behaves exactly like a lottery.

Blocks arrive at random. The chance that your next hash wins does not depend on how long you have been mining. A long dry spell does not make a block "due", which is the same gambler's fallacy that traps lottery players.

The odds, with real numbers

Your chance of finding any given block equals your hashrate divided by the network's total hashrate. The Bitcoin network is currently at roughly 960 exahashes per second (960 million terahashes per second). A hobby miner doing 1 TH/s has a share of about one in 960 billion per block. With 144 blocks a day, that is roughly a 1 in 6.7 million chance each day, or an expected wait of around 18,000 years.

Compared with Powerball

A single Powerball ticket has a 1 in 292,201,338 chance of the jackpot. A Bitaxe-class miner has a chance of about 1 in 5.6 million per day of finding a Bitcoin block, which is more than 50 times better than one Powerball ticket on any single day. A NerdMiner is far worse than a Powerball ticket. Of course the miner runs every day and pays for electricity, while a ticket is a one-off $2. The comparison tells you which "lottery" has the better shot per day, not which is a better deal.

What a block is worth

A block pays the subsidy of 3.125 BTC plus fees, usually somewhere between a few hundredths and a few tenths of a bitcoin in total. At a bitcoin price of about $85,000, a block is worth roughly $275,000 to $300,000. The subsidy halves about every four years, so it falls to 1.5625 BTC around 2028, and the share of the reward that comes from fees can change.

The devices

Prices and specs change. Check the maker's current figures.

The cost: your ticket price is electricity

A Bitaxe drawing about 18 watts uses roughly 0.43 kWh a day, about 158 kWh a year. At $0.15 per kWh, that is about $24 a year. A 3,000-watt ASIC uses 72 kWh a day and costs about $10 a day at the same price, around $3,900 a year. Hardware is on top of that. Compare these with expected block income.

Illustration only: electricity at $0.15 per kWh, block value 3.275 BTC at $85,000, network 966 EH/s. Your costs and the network will differ. Expected income is an average over a very long time, not what you will see in a year.

Documented lucky finds

Because the draw is random, small miners sometimes do win, and each time it makes the news. Reports and pool announcements describe hobbyists finding blocks with Bitaxe devices through public solo pools, including one in November 2025 using several devices totalling about 6 TH/s and another in July 2026 using a single device of roughly 1 TH/s, each worth hundreds of thousands of dollars at the time. Dozens of solo blocks across all sizes are found each year.

Treat them the way you would treat jackpot winners: real, rare and not representative. For every miner who finds a block, many thousands mine for years and never do.

Solo pools and how payouts work

Solo pools such as Solo CKPool and Public Pool let you point your device at a pool server that is built for solo mining: you do not share rewards, and if your device finds a block, the pool pays the whole reward (minus a small fee, often around 2%) to your Bitcoin address. Running your own node and pool is possible and gives you full control. Always use your own receiving address and check each pool's terms.

Is it worth it?

Our guide on whether Bitcoin lottery mining is worth it covers costs and alternatives in more detail.

• As income: no. A small miner earns nothing most of the time, and pool mining pays pennies.
• As a hobby: many people enjoy the tinkering, the open-source community and the long-shot hope.
• As a lottery ticket: it can be fun, with a monthly electricity bill as the price of the ticket.
• As an investment: no. Treat the spend as entertainment, like any lottery ticket.

Risks and scams

• "Bitcoin lottery miner" apps and websites that promise instant payouts are mostly scams. Real mining is hardware and electricity.
• Cloud mining contracts and "mining pools" that ask for deposits often turn out to be Ponzi schemes.
• Fake firmware and clone devices exist. Buy from the maker or an authorised seller.
• Never enter your wallet recovery phrase into a mining tool. A miner needs only a receiving address.

Mining as a lottery versus a lottery you can verify

Both are lotteries with negative expected value. Mining is a fair game by design, since the network checks every block, and your odds are exactly what the maths says. Its drawbacks are cost and the sheer length of the shot. A weekly lottery such as CryptoDrawz offers a very different trade: far smaller prizes, much better odds, a fixed $5 ticket and a draw you can verify, with 90% of sales paid out. They scratch different itches. Whichever you choose, set a budget.

Getting started with a lottery miner, step by step

1. 1Decide your budget for hardware and electricity, and treat it as the price of a long-shot ticket.
2. 2Choose a device: a Bitaxe-class ASIC for a real if tiny chance, or a NerdMiner to learn.
3. 3Buy from the maker or an authorised seller. Avoid unknown clones.
4. 4Create a Bitcoin receiving address in a wallet you control. Back up the recovery phrase offline and never type it into the miner.
5. 5Connect the device to Wi-Fi and enter a solo pool's address and your Bitcoin address as the user name.
6. 6Place it somewhere with airflow, and watch temperature for the first days.
7. 7Check the pool dashboard to see your hashrate and best share. Do not expect to find a block.

Hashrate units and what they mean

Difficulty, halvings and the next few years

Difficulty adjusts every 2,016 blocks, about every two weeks, so blocks keep arriving about every ten minutes whatever the total hashing power. When more miners join, your share shrinks and your odds fall; when miners leave, they improve. The block subsidy halves every 210,000 blocks, about every four years: 50 BTC at launch, 25, 12.5, 6.25, then 3.125 since April 2024, and 1.5625 expected around 2028. A halving halves the reward, so unless the price rises, the value of a block falls. For a lottery miner, that changes the prize, not the odds.

Power, heat and noise

• A Bitaxe uses about as much power as a small light bulb and gets warm. Give it airflow.
• ASIC miners draw kilowatts, are loud and need ventilation and proper electrical circuits. They are not a casual purchase.
• Check local electricity prices before buying. A cheap tariff changes the economics a great deal.
• Never leave hobby electronics unattended on flammable surfaces.

Myths about lottery mining

• "A long dry spell means a block is due." No. Each hash is independent.
• "Mining on my phone will earn Bitcoin." No. Phones are too slow, and apps that promise this are scams.
• "Solo mining is better than a pool." Same average income; different shape.
• "More devices improve my odds per device." Odds scale with total hashrate, so ten devices are ten times the chance and ten times the cost.
• "Mining pays for itself if I win once." On average it does not, and a win is very unlikely.
