About the comparisons
Finding a solo block — calculated per year
Based on your device's hashrate and the current network difficulty. Updates live every time you load the page.
Winning EuroMillions jackpot — 1 in 139,838,160 per ticket
The odds of matching all 5 numbers plus 2 lucky stars in a single EuroMillions draw.
Being struck by lightning — 1 in 500,000 per year
The estimated annual probability of a person being struck by lightning, based on commonly cited statistics.
Rolling 5 sixes in a row — 1 in 7,776 per attempt
The mathematical probability of rolling a six on a standard die five consecutive times. (1/6)⁵ = 1/7,776.
Formulas
Chance per block = Your Hashrate / Network Hashrate
Each of the 144 daily blocks is like a lottery draw. Your odds of winning each draw equal your share of the total network hashrate.
Chance per day = 1 − (1 − chance per block) ^ 144
With 144 blocks mined per day, this calculates your cumulative probability of finding at least one block. The same logic extends to monthly (×30) and yearly (×365) odds.
Block reward = 3.125 BTC + transaction fees
When you find a block, you receive the full block reward plus all transaction fees in that block. The reward goes directly to your wallet — no pool, no middleman.
Solo vs. Pool mining
Solo mining
You mine independently and keep the entire block reward when you find one. Lower probability, but the full reward is yours. No KYC, no fees, no third party.
Pool mining
You combine hashrate with other miners for more frequent, smaller payouts. Pools typically charge 1–2% fees and may require account registration.
Important notes
- Mining is probabilistic — you could find a block on your first day or not for years. The odds shown are statistical averages, not predictions.
- Network difficulty adjusts roughly every 2 weeks. As more miners join the network, difficulty increases and your odds decrease.
- The block reward halves approximately every 4 years. The next halving (expected ~2028) will reduce it from 3.125 to 1.5625 BTC.
- These calculations are based on current network conditions and are for informational purposes only. This is not financial advice.
How we calculate
Formulas
BTC/day = (Hashrate / Network Hashrate) × 144 blocks × 3.125 BTC
Your miner's share of the total network, multiplied by the daily block rewards. 144 blocks are mined per day, each worth 3.125 BTC.
Revenue = BTC/day × BTC price
The BTC price is fetched live from the blockchain.info API and converted to your local currency.
Pays for itself = Product price / Monthly revenue
How many months of mining revenue it takes to cover the purchase price.
Scenarios
Conservative
BTC price −30%, difficulty −5%. (Shows scenario if conditions worsen)
Current (Live)
Today's actual BTC price and mining difficulty.
Optimistic
BTC price +100%, difficulty +20%. (Shows scenario if Bitcoin grows)
Important notes
- Electricity costs are not deducted. Actual profit depends on your local electricity rate.
- Mining difficulty changes roughly every 2 weeks. Higher difficulty means lower earnings.
- Pool fees (typically 1-2%) are not deducted. Most miners use a mining pool.
- The block reward halves approximately every 4 years. The next halving will reduce it from 3.125 to 1.5625 BTC.
- These calculations are estimates based on current network conditions. Actual earnings may vary. This is not financial advice.
