If the bitcoins from satoshi wallet will be sold, how will cost bitcoin? We are talk about 980 000 btc, what will be in this situation

I hardly can imagine how Satoshi or someone else would be able to sell 980 000 at once. But if, then it would huge crash, maybe Bitcoin will come back to hundreds and to recover we would need at least several years. But even if part of these BTC would be sold or move to another wallet address, it would have big impact to price of BTC, not into positive side offcourse
