Lottery miner explained: how a Bitaxe finds a whole block

A lottery miner is a small home miner that mines solo – i.e. tries to find a complete Bitcoin block entirely on its own. If it hits, there is the full block reward; if it does not hit, there is nothing. Hence the name: it is a lottery with a very high jackpot and a very small stake.

How does the block lottery work?

Bitcoin mining is at its core a gigantic guessing game: miners look for a number with which the next block hash falls below a target value set by the network. Each attempt (hash) is like a lottery ticket. Your Bitaxe generates over a trillion of them per second – but the entire network does a hundred million times more. Whoever finds the matching value first gets to write the block and collects the reward.

What do you get from a hit?

Currently the block reward is 3.125 BTC plus the transaction fees of the block – depending on the price, several hundred thousand euros, for a single found block. With a lottery miner this entire sum goes to you, because you mine solo and not in a pool.

How high is the chance, concretely?

Honestly: very small – but never zero. Your share of the global hashrate determines the probability. At a network hashrate in the order of ~800 EH/s, roughly:

  • Bitaxe Gamma (~1.3 TH/s): on statistical average one block every ~12,000 years.
  • NerdQaxe ++ (~4.8 TH/s): on average every ~3,000 years.
  • NerdOctaxe (~12 TH/s): on average every ~1,300 years.

That sounds hopeless – but statistically it is not entirely: every single block (every ~10 minutes) is a new, independent attempt. In recent years there have been several documented cases where exactly such a tiny miner actually found a block. Unlikely does not mean impossible.

More hashrate = better chance

The more hashrate, the higher the hit probability – linearly. A NerdOctaxe with ~12 TH/s has roughly ten times the chance of a single Bitaxe. Still, nothing is guaranteed, and whether the extra consumption is worth it depends on your motivation. Whether operation pays off overall is examined in Solo mining – is it worth it?

Approach it with the right attitude: you pay a few euros of electricity for an exciting hobby – and the possible block is the icing on the cake, not the plan.

Want to draw a ticket yourself? The cheapest entry is the Bitaxe Gamma 601, the best block chance is offered by the NerdOctaxe.
