Solo Bitcoin Block Won With Rented 100 PH/s Burst, Netting $200K Payout

A lone Bitcoin miner captured block 960,804 at 02:11 UTC on Monday, collecting 3.15689830 BTC—roughly $200,000 at current prices. The block included the 3.125 BTC subsidy plus about 0.032 BTC in fees from 4,243 transactions, and it marked the 317th solo block found via CKPool. The winning address: bc1qdyqjq9qccp34pyv3kxmsrkn7p0amnsqqy8kdeq.

What actually stands out isn’t the dollar figure—it’s the method. CKPool’s operator noted the miner’s “wildly variable” hashrate peaking near 100 PH/s, almost certainly rented. With network hashrate around 924 EH/s, that burst represented roughly 0.011% of the network, translating to an expected cadence of one block about every 64 days at that peak. Contrast that with a single 100 TH/s box: odds hover near 1 in 62,750 per day, or an average wait approaching 172 years.

This is the modern face of “solo” mining: less basement romance, more tactical variance trading. Hash rental markets let participants buy a slice of probability for a limited window, point it at an endpoint like Solo CKPool (which lets miners participate without running a full node), and accept the variance. CKPool takes a 2% cut if a block hits. That’s not mining as an income stream; it’s closer to buying an out-of-the-money option with defined cost and lumpy payoff.

A few observations on the strategy: - Economics: At 100 PH/s, you’re purchasing time against the global hashrate. If you can source hash below its fair-value break-even (after fees, reject risk, and CKPool’s 2%), your expected value can land near neutral while preserving upside skew. It’s not trivial; but some operators time bursts when fee markets spike. Notably, fees here were only ~0.032 BTC, so the win wasn’t juiced by a mempool surge. - Psychology: The lottery pull is real. April saw a 70 TH/s miner walk away with about $225,000; a week earlier, another bagged roughly $210,000. Prior solo wins hit around $266,000, $365,000, and $350,000. Those USD swings track price, not probability. The block reward is fixed at 3.125 BTC until the next halving at block 1,050,000—expected spring 2028—when it drops to 1.5625 BTC. - Infrastructure: CKPool lowers friction for anonymous solo attempts by handling the node and block template side. That convenience expands participation but also concentrates trust in the template source. It’s a trade most small operators are willing to make for simplicity. - Network dynamics: Rented hashpower is fluid capital. In normal volumes, it marginally improves hashrate elasticity and decentralization at the edges. In concentrated bursts, it can feel mercenary. The 100 PH/s here is tiny against 924 EH/s, but the pattern—short-lived, portable compute—will likely persist.

Context didn’t slow the chain. The block landed “despite the chaos” from the recent Coldcard hardware wallet exploit, where losses have been estimated near $114 million. Bitcoin itself changed hands around $63,700 on Monday, up about 1.1%. On prediction platform Myriad, traders currently lean cautious, putting roughly a 68% chance on a move to $55,000 before higher levels.

The takeaway for miners and allocators is about intent. Pooling smooths cash flow; solo via rental concentrates risk in time. One isn’t better; they serve different mandates. If your goal is steady sats, join a pool. If you’re sizing a small, asymmetric bet and can source competitive hash, a time-boxed solo burst can be rational—especially before the 2028 halving halves the subsidy to 1.5625 BTC and further compresses the upside. Either way, be precise about costs, counterparty risk, and the true odds you’re buying.
