$300 Second-Hand Mining Rig Strikes Gold with $230,000 Bitcoin Block

According to community reports, a Bitcoin miner using a second-hand mining rig worth only $300 successfully mined a block on its own, earning a reward valued at approximately $230,000. This incident highlights the lottery-like nature of solo mining, but the probability of such an event is extremely low, and most miners rely on mining pools for stable returns. As mining difficulty continues to rise with increasing hashrate, the chance for a retail-grade miner to find a block alone has become vanishingly small, making this an act of sheer luck rather than a repeatable strategy.
