This is not burn because we don't know if it's spendable or not. Satoshi still has access to his entire wallet, but he isn't touching it. I don't believe the Bitcoin creator would lose his private keys, which he is very familiar with. The sender would illustrate why he sent four Bitcoin to the Satoshi address. I believe it is an error. Because there is no reason for anyone to send this amount consciously.
I would argue that Satoshi may not have the keys to this address. When BTC is unspendable or out of circulation, then its value grows. Therefore, "forgetting" or "losing" their keys, Satoshi actually adds value to the existing bitcoin in circulation
Well since we haven't heard from the guy I guess it's safe to say that he lost his keys, or maybe even did the same things you stated lmao. kiddings aside I can point to clout as to why they did this. They wanna be topical and be talked about probably in this forum, and they succeeded coz now we're talking about them.
As I said before, probably Satoshi "lost" his keys. Maybe he just sent the mined BTC to the addresses and then got rid of the keys for all of them.
If Satoshi is even alive still. ...

That is a bit of a horrible thought, is it not? Satoshi dies without anyone ever knowing who he was in the end.
I don't believe Satoshi is dead. I strongly believe Satoshi was a student of Hal Finney's. Hence, the first transaction ever made was from him to Hal Finney.
