A solo miner mined a bitcoin block and received 3,131 BTC ($289,191) after renting hashpower from NiceHash for $90.

Block reward and payouts

The miner’s payout totalled 3,131 BTC, recorded in the block’s coinbase transaction and credited to the miner’s address.

After accounting for the rental expense of $90, the net result remains substantially above the cost of rented capacity in this instance.

How the hashpower was obtained

The participant used NiceHash, a marketplace for renting hashing capacity, to acquire the compute power required to find a valid block.

Renting on demand allowed the miner to assemble transient capacity without owning ASIC hardware, and the fee paid for that capacity was $90.

Context for solo mining events

Solo mining yields high variance: infrequent blocks can produce large rewards, while most attempts generate no immediate return for the miner.

Using rented hashpower changes cost structure and risk profile, as short‑term expenses replace ongoing capital investment in physical equipment.

The episode illustrates that occasional successes in solo mining can result in outsized payouts relative to short‑term rental costs, while remaining atypical for most participants.
