"not sure how it will affect the upcoming price!" - 600 BTC is nothing. It will not move price in any direction.
Not even 10 times as much would mean anything when it comes to price. But if, say, those 600 BTC ended up in the hands of someone famous like Bezos or Gates, it would already mean that a massive FOMO train would start. Saylor regularly buys BTC in the thousands (5050 BTC 10 days ago) and almost no one considers it anything positive anymore.
