What caused BTC hashrate drop?

TLDR

Bitcoins hashrate dropped mainly because authorities shut down large mining clusters in Chinas Xinjiang region, taking an estimated 400,000 machines offline and removing roughly 80100 EH/s of capacity, the steepest fall since the 2024 halving exchange coverage.

1. Magnitude: the 30?day hashrate fell from about 1.1 ZH/s to just above 1 ZH/s, roughly an 810% decline market report.
2. Confirmation: multiple reports tie the dip to Xinjiang shutdowns rather than weather or hardware issues industry coverage.
3. Near?term effect: difficulty is projected to adjust down by around 3%, which should partially offset miner revenue pressure market report.

Deep Dive

1. China Enforcement

The immediate catalyst was a coordinated shutdown of mining farms in Chinas Xinjiang region, with estimates of roughly 400,000 machines going offline. That equates to about 80100 EH/s depending on unit assumptions, and marks the sharpest decline since the halving in April 2024 %%CKPROTECTED0%%.

China still contributes a meaningful slice of global hashrate despite earlier bans, so concentrated enforcement can shift network metrics quickly. Reports this week attribute the dip to local crackdowns in Xinjiang rather than transient weather or equipment failures industry coverage.

2. Size and Context

On a 30?day basis, Bitcoins hashrate fell from roughly 1.1 ZH/s to just over 1 ZH/s, an 810% pullback that aligns with estimates of 80100 EH/s exiting the network. It is the steepest post?halving decline reported this year market report.

Importantly, hashrate is inferred from block discovery and difficulty rather than observed directly, so figures are estimates, but multiple independent sources pointed to the same magnitude and timing tied to the Xinjiang shutdowns exchange coverage.

3. What Happens Next

Short term, lower hashrate can slow block times marginally until the next difficulty adjustment. Current projections point to about a 3% difficulty decline, which would reduce the hash?per?block threshold and offer partial relief to miner revenues market report.

Historically, hashrate relocates as power and policy conditions shift, and the protocols difficulty mechanism rebalances block cadence. This is consistent with prior episodes where regional crackdowns caused temporary hashrate dips that normalized over ensuing adjustment periods industry coverage.

Conclusion

The hashrate drop was driven by concentrated miner shutdowns in Chinas Xinjiang region, removing on the order of 80100 EH/s and producing the sharpest post?halving decline this year. The networks difficulty should adjust lower, easing conditions for remaining miners and normalizing block times over the next adjustment window.
