What would happen if Satoshi Nakamoto’s wallet became active?

With several stories in the past weeks of Satoshi era bitcoin wallets showing signs of activity after years of lying dormant, I began to ponder what would happen if Satoshi’s wallet were to become active?

From what I understand, this wallet which contains over 1 million bitcoin, is one of the largest, if not the largest, holders of bitcoin. So much so that if it were to show any signs of movement on the blockchain it would crash the bitcoin value altogether because it is assumed that these coins are burned and forever untouchable.

I don’t know if that is a fact or just something that I read here in passing, but with so many dormant wallets becoming active again I was wondering what effects some of these satoshi era and silk road era whales would have on the market?
