Why?? The only thing that makes any sense is that the sender is flushing Satoshi out.
Under the new IRS rules, you have to report any receipt of crypto over $10k. So, Satoshi has to dox himself, OR break the law
That
might make sense under certain conditions, though I'll be damned if I can think of any legitimate ones where someone would send that much bitcoin to Satoshi's address just on the off chance that he'll somehow come out of hiding to avoid breaking the law. Somehow that just doesn't jibe with anything a reasonable person might do, even if that person had enough bitcoin to throw away.
I did read some thread titles dealing with this, but I never looked into it until now. This is the first time anything's been sent to Satoshi's stash, right, or am I wrong on that? I know no coins have been sent from the genesis block, but my knowledge of the reverse scenario is fuzzy at best. Aside from that, it's just another wacky story from the world of bitcoin--there have been hundreds of them by now, with more to come no doubt.
