⛏ A lucky solo miner mined a block and received a reward of 3.433 BTC ($218,000)

Solo mining is mining without joining any pool. In this case, it is much more difficult to obtain a block and the probability of this is extremely low. But you take all the profit for yourself without sharing it with other pool participants. This is a kind of lottery game - the chance of winning is small, but the reward is large.

15 hours ago, a solo miner with a hashrate of ~120 PH/s added block 841,286 and earned more than $200,000. Judging by the hashrate, this is a fairly large miner.

This happens periodically. In total, according to ckpool pool administrator Kon Kolyvas, in the entire history of Bitcoin, 282 blocks were added by solo miners. This case is notable because it is the first after the fourth halving.
