Friday's record push to $1,023 triggered a rush of hashpower, briefly sending network solrate past 30 GSol/s for the first time, according to The Block. The catch is that miner revenue came in about 3% lower than when ZEC traded below $900, because the new competition arrived faster than rewards could keep pace. Falling profitability during a price rally is an unusual combination, and it is worth watching for what it means for network security incentives if it persists.
