Bitcoin miner wins 6.25 BTC block reward solo.

  • A single Bitcoin miner successfully solved block 793607, beating the odds and earning the 6.25 BTC block reward.
  • The miner used an Antminer S9 with a capacity of about 17 TH.
  • Considering the current Bitcoin mining difficulty and with 17 TH, it would take a solo miner an average of 450 years to solve a block.

As the price of Bitcoin struggles to surpass $26,000 and the broader cryptocurrency market is affected by recent regulatory events, there has been little to celebrate for Bitcoin enthusiasts.

However, a solo BTC miner recently hit the jackpot by winning a block reward. According to on-chain data, the miner successfully mined block 793607, earning the 6.25 BTC block reward against all odds.

BTC miner with single Antminer S9 hits jackpot

The solo miner accomplished this incredible feat using a single Antminer S9, which generated only 17 terahashes (TH). Their “lottery” win was worth around $160,000 at the time of the block reward.

“Congratulations to miner 151XTfHBfaDqoNWGGeYobNX2YzFFWuB5YD with only ~17TH for solving the 275th block at! That is likely a single S9 miner. A miner of this size would only solve a block once every ~450 years on average,” tweeted Con Kolivas, a CGMiner software engineer and the admin of Solo CKPool.

This is not the first time that a solo miner has won such a jackpot, with CKPool reportedly seeing seven such instances since January. However, this feat is becoming increasingly difficult as the Bitcoin hashrate and mining difficulty continue to rise.

According to data from, the current Bitcoin mining difficulty is 51.23 trillion hashes. Mining difficulty measures how difficult it is to mine the next block, i.e., how many hashes a miner must generate to find and solve a valid block. The current difficulty is at an all-time high, with most blocks being solved by major mining pools and companies.

The difficulty is adjusted every 2016 blocks (approximately two weeks) and can increase or decrease. The next adjustment, expected on June 14, will see the difficulty increase by about 2.92% to 52.73 T.
