I invested around 15k the day before the crash on Nvidia. i still have around 94k uninvested. What should i invest into?

Ive been thinking about gold since it usually goes up when the dollar drops, especially during crashes like the one we’re seeing now. Also looking at Microsoft and Google since they’re on a big dip right now seems like a decent entry point. I’m leaning towards investing in ETFs like the Nasdaq-100 and S&P 500, but I’m not sure how to split it up. Any suggestions on allocation? Or maybe better ETFs/stocks I should be considering?
