There will be a temporary massive panic in the BTC market if/when Satoshi starts to sell his huge pile of virgin coins. This will present a great opportunity for people with the guts to go against the crowd. The damage could be more severe and long-lasting if it combined with bad news related to the on-going post-FTX drama, and more countries "banning BTC", etc. Our bear markets get pretty predictable after a while, but the FTX hangover is real and not over with yet.
What if also coins are moved out from other wallets to the Genesis wallet or any other wallets rumoured to belong to Satoshi? What do you think will happen to the price of Bitcoin? It will spike, right? Well, I would think that if coins begin to get sold from these wallets now that we're in a bull run it won't cause much panic. People will hardly notice it. Panic might come if it were done in the bear season but definitely not now.
