Satoshi Nakamoto does not use very old wallets and coins to avoid unwanted attention. He has been cashing out anonymously mined funds since 2010. This hypothesis was voiced on the BTCparser project website.
"My theory focuses on the money, not the personalities, and this leads me to think that the mysterious megacat of 2010 could be Satoshi himself or a member of [his] Satoshi organization," the author noted.
According to the theory, after leaving the public space, the creator of the first cryptocurrency began to mine Bitcoin anonymously and accumulated significant wealth. In 2010, he created numerous wallets, each containing 50 BTC.
Since then, the programmer has been using these means, gradually 'awakening' them from a long slumber. The original wallets from 2009, associated with Satoshi's online persona, were left untouched for privacy reasons.
The author compiled a list of the presumed Satoshi wallets based on a set of criteria:
all the coins on them were mined shortly after Bitcoin's launch, but after Satoshi's disappearance;
exactly 50 BTC were stored in all wallets, no other transactions were recorded until the 'awakening';
the funds are combined at one P2SH format address (usually used as an escrow) and sent in equal parts to several bech32 addresses.
Since 2019, the researcher has been monitoring the selected addresses and found that during this time, 24,000 BTC were withdrawn from the 'awakened' wallets of the presumed Satoshi.
The first alleged cash-out of coins occurred in November 2019. The last one — on November 15, 2024 — involved the 'awakening' of 2000 BTC across 40 wallets with a total value of about $176 million.
According to the author, Coinbase is presumably aware of the identity of the 'megacat' from 2010, as it was to this platform that coins from the dormant addresses went.
Let us remind you, programmer Peter Todd still refutes the conclusions of the HBO documentary where he was named the creator of Bitcoin.
