BTC trading all hours, almost always an indicator which way the market goes when it's opens

I've only looked it since YTD so 3.5 months or so but the implied moves is almost 100% accurate

if it's moving a decent amount before the market opens the market just moves whichever way btc is going?

I honestly don't remember too many days when btc premarket doesn't move the same direction as nasdaq when it opens.
