The clue was given by an address that collected 50 bitcoins from a mining reward that had shown no signs of activity since February 2009, a month after the creation of bitcoin, suggesting it could be the Satoshi Nakamoto himself.

According to Blockchair.com data, those 50 BTCs were transferred to two virtual wallets, and Nakamoto's fortune is known to be deposited in several different wallets. After that, the transaction becomes almost impossible to trace, since by the very structure of the network it was subdivided into a complex chain of results.
