The coins that was moved, was linked to a regulated exchange..... do you really think Satoshi Nakamoto would use regulated exchanges if he wanted to hide his true identity? Regulated exchanges link Bitcoin addresses to actual true identities of specific people, so making use of these exchanges will reveal your true identity.
This is most probably some early miner that are known to everyone that are simply selling some early coins just to test the integrity of these exchanges. If his tx is linked to his true identity and this information is leaked... then he/she would open up a whole can of worms.
Just ignore this and just move on.
Satoshi Nakamoto had a lot of people helping him to test the mining back then and these coins was mined in February, if I am not wrong.
Perhaps not the whole cryptocurrency world, but a significant part discusses this situation and monitors the further development of events. I believe that these regulated cryptocurrency exchangers in any case follow what is happening. And if these cryptocurrency exchanges have all the available information, including data on the verification of their customers, then it is quite possible they know who carried out these transactions and who owns these bitcoins now. but somehow everyone is silent, maintaining the intrigue. Of course, I understand that any administration of the cryptocurrency exchange maintains the confidentiality of its customers, but nevertheless, it would be possible to shed light on this mystery covered in darkness.
