About to come into $5K -$10K… what should I invest in?

So I'm about to come into anywhere from $5K-$10K that I really don't need at the moment. I'd rather invest and treat it as money I never had. Would love to use this as a jump start for my kids college fund, so I'd be looking at cashing out somewhere around 2030-2035.

What would you invest in knowing you were going to let it ride for 5-10 years?

Right now, I have roughly 3000 XRP and a very tiny fraction of one BTC. Also put a couple hundred into SHIB due to fomo a few years back as well, but that's the extent of my crypto portfolio.
