84% of BTC Hashrate Backed Bitcoin DeFi in Q1 — But Miners Captured Almost None of the Fee Revenue

Bitcoin's DeFi ecosystem leaned heavily on the network's security apparatus in Q1 2026, with 84% of total hashrate underpinning Bitcoin DeFi activity — yet the miners providing that security saw almost none of the associated fee upside. The disconnect points to a structural gap between network utilisation and miner compensation.

Compounding the problem, hashrate has been falling even as BTC prices rallied, a signal that the rally hasn't been strong enough to pull offline machines back into production. Miner profitability metrics have slid to levels historically associated with large-scale shutdowns, squeezing operators who were already running thin margins after the most recent halving.
