Which game earns you real money?

In the realm of cryptocurrency and finance, I've often been curious about which "game" truly offers the potential to earn real money. Is it through trading cryptocurrencies, mining for coins, investing in Initial Coin Offerings (ICOs), or perhaps participating in decentralized finance (DeFi) protocols? Each avenue seems to promise lucrative returns, but which one stands out as the most viable and reliable way to generate actual financial gains? As a professional practitioner in this field, I'm keen to understand which "game" you would recommend for someone looking to earn real money in the crypto and finance world. Could you elaborate on the strategies, risks, and potential rewards associated with each option?
