Whale Alert
Addresses that mined 50 BTC in seven blocks between 43,361 and 43,871 moved their holdings yesterday, in one of the more clustered dormant-coin events of the year. The blocks fall in a narrow window from late 2009 into early 2010, each carrying the pre-halving 50 BTC reward.
The cluster matters because early-miner coin movements are often read as signals, but they are only signal when the source is identifiable. The tracker behind the moves ruled out Satoshi authorship, narrowing the read to a known cohort of early miners rather than the pseudonymous creator.
The 50 BTC reward era ended at block 210,000 in November 2012, and addresses that mined in that window have been largely dormant for more than a decade. Movements from this cohort are increasingly rare and are tracked closely by on-chain analysts watching distribution patterns ahead of any future supply shocks.
Frequently asked questions
-
What blocks did the seven early-miner addresses mine?
The seven addresses mined in blocks 43361, 43452, 43647, 43680, 43765, 43855, and 43871, all carrying the pre-halving 50 BTC reward.
-
Were any of these blocks mined by Satoshi?
According to the tracker, none of the seven blocks were mined by Satoshi, which narrows the read to a known cohort of early miners rather than the pseudonymous creator.
-
Why does ruling out Satoshi matter for analysts?
Dormant-coin events get framed as creator-driven when authorship is unclear; ruling out Satoshi shifts the read to early-miner distribution patterns rather than founder-treasury activity.
-
When did Bitcoin's 50 BTC block reward end?
The 50 BTC reward era ended at block 210,000 in November 2012, when the first halving reset the block subsidy to 25 BTC.
-
How often do 50 BTC-era miners move their coins?
Movements from this cohort are increasingly rare; addresses that mined in the 50 BTC era have been largely dormant for over a decade and are tracked closely by on-chain analysts.
