... but there remains the issue of Satoshi dying and creating a massive capital gains / estate tax liability. When it comes to Satoshi's coins I am far more concerned about Satoshi's estate than Satoshi.
Satoshis coin are forever a dark cloud hanging over the markest, I think he deserves his fortune but it is what it is, like any coin with premine or instamine these coin could be dumped at any time, we can't ever be sure if he still has the private keys or someone else is or will be in possession of them and will ever move or dump the coins, it is an eternal state of uncertainty.
Idk if I remember correctly, but I remember seeing a thread somewhere on here that Satoshi actually did move his coins... Is there any validity to this?
That was a bug from one of the block explorers where a fake transaction hash got injected and subsequently approved because their script was buggy. Obviously fake, since no other block explorers were showing the transcation.
@Melbustus: Regarding Satoshi's coins, I dug up a past reply of mine that perfectly suits the current scenario with his coins as well:
Monero has the advantage that, unlike with Bitcoin, you can't track the blockchain for incoming deposits at exchanges nor measure the amount of Bitcoin days destroyed. I've witnessed multiple occasions where people started dumping based on Bitcoin days destroyed.
