There are lots of ways to live your live, and achieve some happiness, either now, ongoing, or merely in the future.
It sounds like you found one method that creates some measure of happiness for you, right now. Will anything in your future change the variables so that you have to adapt? What will your options be then?
Now, your premise here is "so much focused" or to reword, "intently focused" on growing wealth for the purposes of financial independence. If you start with that premise, there might a a corresponding decrease or minimization of competing focuses, including "what makes you happy in the present."
If you shift the premise a bit to more of a Pareto Principle approach of "do at least the 20% you need to plan for your future, and get 80% of the benefit", you might see things a little differently. Extremes don't make for good arguments, but they can be illustrative. If you feel like you have to spend "everything" you have, and invest "nothing" then any break in your income stream will instantly crush everything that you currently use to make you happy. If, on the other hand, you find that you can be really quite happy while spending 75% and investing the other 25%, you might find that over time, you've been happy all along, and you've gained a resilience to changing life circumstances as well, and increased your options for what you are required to do, and what you can choose to do.
As for just "investing" or "not investing", the common wisdom is that simple savings will tend to lose value when adjusted for inflation. You do not need to become "busy with cryptos" to invest, though. You can simply think long-term, buy broad total market index funds, and stop thinking about those investments almost instantly. It does not take focus. You don't have to go all the way down the rabbit hole to intently focus on what you might consider absolutely optimizing your investments. It's quite unlikely to pay off, so take a simpler path.
