Solo miner with 70 TH/s defies 300-year odds to claim $222K Bitcoin block reward on CKPool

An S17+ from 2019 — hardware most farms scrapped two generations ago — just pulled 3.128 BTC off a 1.02 ZH/s network while running 0.0000069% of total hashrate. This is CKPool's second solo hit in 10 days (block 943,411 landed around March 30), and their 313th lifetime solo win since 2014 launch. Post-halving EV on 70 TH/s works out to roughly $2/day against $5-6 in power costs, so every one of these miners is consciously running a negative-EV lottery — but $222K on a single deprecated ASIC is the kind of variance that keeps the solo mining cult alive.
