I don't "invest" to make money. It's a currency. I buy it to use it. I might have to hold it for 5 years, maybe 10, maybe 30, or maybe I'll die and crypto will never be successful (a sad thought but possible).
But in the meantime I'll do what I can to improve adoption. That includes working on core protocols, improving UX for non-technical users, or writing software that helps vendors with payment integration. I also make an effort to approach business and show that there is demand for crypto payments.
This is literally the only way to make crypto successful. All this price action non-sense, and people wanting to get fiat-rich is just unproductive noise to me.
