A single Ether miner hit it big when they mined a block on their own and received a reward of roughly $540,000. On Jan. 17, the miner mined a complete block and received 168 ETH while using the 2miners Ethereum SOLO pool. This payment far exceeds the per-block average reward of around 4 ETH. The size and hash power of the SOLO pool add to the reward's exceptional nature.
