Some fool sent thousands of ridiculously small transactions (546 sats) to Mempool for a ridiculously large price (over 500sats/vB) and the reward per mined block rose to over 10BTC.
Market forces have set in motion and hashrate is disappearing from small pools to the largest ones (Foundry and AntPool). Noble principles aside, everyone wants their portion of the bear. (OCEAN from 1.3Eh/s to 380Ph/s)
