Next Bitcoin difficulty adjustment
Loading current Bitcoin data
Connecting to live sources…The current estimate of how Bitcoin mining difficulty may change at the next retarget.
What it means
Bitcoin recalculates mining difficulty every 2,016 blocks. This percentage estimates the upcoming change from how quickly blocks have arrived during the current period.
Why it matters
The adjustment is the protocol's mechanism for bringing average block production back toward ten minutes as network hashrate changes.
A positive estimate means difficulty is currently projected to rise, making block discovery harder at the next retarget.
A negative estimate means difficulty is currently projected to fall, making block discovery easier. The estimate can change until the retarget occurs.
