CKPool Miner Wins Big with $200K Bitcoin Block Reward
A solo miner on CKPool has struck it big, solving a Bitcoin block worth an estimated $200,000 in rewards. The miner rented a whopping 100 PH/s of hashrate, which peaked at that rate and earned them a tidy profit. With the cost of renting this capacity coming out to about $25,000 per week, this represents a remarkable return on investment - roughly 8x their expenses.
The block reward came in at 3.125 BTC plus transaction fees, a standard figure since Bitcoin's fourth halving in April 2024. What makes this case interesting is that the miner didn't own the hardware; they rented it from a cloud mining or hashrate marketplace and pointed it at CKPool's solo mining infrastructure.
CKPool operates with a 2% fee structure, requiring no registration or operator wallets, making it a relatively frictionless option for miners who want to roll the dice without committing to long-term infrastructure. This isn't the first time rented hashrate has paid off on CKPool - in February 2026, a miner reportedly rented just 1 PH/s for approximately $75 and managed to solve a block.
CKPool's data shows dozens of solo mining successes throughout 2025 and 2026, suggesting that despite rising network difficulty, the strategy retains a dedicated following. However, the risk is real - for every miner who hits a jackpot like this one, there are likely many others who rented similar hashrate and came away empty-handed.
