Awesome answers here.
I'd definitely diversify and invest something in crypto, but the majority I'd invest into building a profitable niche site, and then flip it. I've already built a few websites and flipped it for 10x - 20x of their monthly income. It would be way easier to do it with a few thousand to invest in writers and SEO work. The first website that I've ever built was around calisthenics equipment like 6 years ago. Nothing special, just regular reviews and guides. After a year of working on it, I totally neglected the site but wanted to keep it alive. 3 years later, the site was ranking for many buying keywords and I've started to earn about $500 per month on Amazon. Just reinvested that money into content building and SEO work and boom, a year later we were able to flip the site for $30,000.
I suppose if I had the capital, it would be way easier and faster to reach that amount. Currently, I'm building Region Vavid, and that's definitely where the majority of my money would go.
