@OP, this is not something new and it should be count as a baseless statement because no genuine evidence was use to back the claim if the wallet was indeed Satoshi's own.
I hope that 1 millions of satoshi bitcoin will be never touched, overwise it will dump btc so hard
It will start going down but you know what? that's what most of the investors want.
You cant possible speak for every investors cause you dont what people want and the last time i checked most investors have prepared for the halving while they are now expecting bullish price trend.
With that been said, i think you dont understand what @Sword555 was trying to say when he said price will dump so hard, he mean really hard.
