The best advice that I would give is to invest into gaming and cryptocurrency. With the recent development in the gaming industry and its shift to new technology, these platforms that were previously considered as 'niche' are flourishing in the market. The traditional investments (e.g. gold, stocks, real estate, etc.), while lucrative, but they are mainly geared towards long-term investment.
In cryptocurrencies, the possibilities are endless due to its volatility that many investors are taking advantage of. One can earn significant amount of cash relative to the time.
I feel the same way. "pay to win" was a thing loong before crypto ever started, and all those mobile gaming industry made profit based on selling gems and life and whatever to keep people gambling more, they spent literally hundreds of millions of dollars yearly to promote their games just so they could sell some more in game stuff. Mostly free games that you buy things to further into easier without grinding too harshly.
This is just mobile part, don't get me started with all the games that are selling "skins" and so forth that made billions of dollars every year. Imagine those huge games like GTA or even angry birds, all getting into crypto and blockchain world, either with NFT or some other method. They would really be insanely hard to stop. This is why I believe that gaming and blockchain world will get together eventually, maybe today it already started with Axie, and that could be the direction games may take, who knows?
