Satoshi is gone for good. If he wanted to cash out, he'd have cashed out already. If he wanted to reassure the world that those coins are gone, he'd burn them by moving them to some known black hole address. The fact that the coins are still there after all that happened with bitcoin and finance and multiteradollar marketcap can have two explanations:
1 - Satoshi is gone for good
2 - Satoshi likes to keep bitcoiners on their toes
I lean towards 1.
Its not like we have an exact list of satoshis address, for all we know he already cashed out like 1 million and hes just living off of that and biding time for whatever his grand plan is
