Bitcoin has risen nearly 22% in seven days, climbing from a low of $62,679 on August 17 to a high of $81,265 on Tuesday. The rally increased the estimated value of Satoshi Nakamoto's Bitcoin holdings by as much as $15 billion. Arkham Intelligence maps about 1.096 million Bitcoin across roughly 22,000 addresses believed to be associated with Bitcoin's pseudonymous creator, although the exact amount remains uncertain. At Bitcoin's current price of $78,280, Arkham values the holdings at $85.82 billion, up from $71 billion before the rally and slightly below the previous day's peak of $87 billion, when Bitcoin exceeded $81,000. The coins have remained untouched over the years, making Satoshi one of the largest potential individual Bitcoin holders. Separately, Galaxy Research reported that 40 BTC received on May 28, 2012, moved after roughly 14.2 years of inactivity in block 964127. The recipient was identified as Boerse Stuttgart Digital, while no sender attribution was available in Galaxy's database. The coins were worth about $200 when acquired at roughly $5 each and about $3.14 million at the time of transfer. Galaxy estimated realized profit of roughly $3.16 million, equivalent to a 1,535,911% gain.
