If it's "poured" into the market, the value will crash so whoever's trying to sell them won't make as much money. That said, at this point, any activity in that wallet will cause a huge stir in the community.

That said, there's probably a nontrivial amount of processing power currently being used to crack that wallet / find the secret key.

A theory is that Satoshi themselves lost access to their own wallet, so if there is activity, it may mean someone got the private key.

Anyway yeah, it is a huge risk, and it's proven by the billions scammed from people when new coins were created and the creators themselves held onto a lot of the coins themselves to sell when the hype cycle is trending upwards.
