I don't know who needs to hear this, but you can still become Bitcoiner. It's easy, the best is to approach a Bitcoiner you already know (a friend or a friend of a friend).

You can still front run mega corporations turning their cash reserves into bitcoin.

If you keep your productive energy in fiat, it evaporates. If you consume it, entropy will take it - even memories fade with time, although make sure to make them.

It does not really matter much if you earn Bitcoin or you buy it. Don't overcomplicate. Self custodial wallet, buy and play.

Everything else will come with time - hardware wallets, inheritance, backups, deeper understanding. Just don't be that person that knows about bitcoin but does not have a personal experience with it.

At a later stage you might want to read Cryptocurrencies: Hack your way to a better life, in order to learn about many fun things you can do with Bitcoin. This one is unique that it shows you practical things, not only "we'll all be rich" hopium.
