Earning Bitcoin
Earning is a great way to acquire bitcoin.
Do not forget about earning bitcoin. It is one of the best ways to acquire bitcoin, mostly because you can obtain it without having to hand over identity information to a trusted third party.
A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution.
Who would've thought, eh?
If you have a skill, talent, product or service that you can deliver in return for bitcoin, put it out there. Let the free market reward your time, effort and energy in the best form of money man has ever created, a money that no man can just print out of thin air.
If you've got a product/service, the best place to put yourself out there is on the world wide web (obviously). The next best place is at bitcoin meetups and conferences. You're likely to get more eyes on your business from people who actually own bitcoin. I've seen all sorts of products and pamphlets at the back table of bitcoin meetups and conferences. If you've got a physical location, consider putting yourself on btcmap.org. If you're Australian, consider getting yourself on the Orange Label Directory.
You can use BTCPayServer as your payment processor, or even keep it simple using Wallet of Satoshi, but be sure to self custody your bitcoin after it gets to a meaningful sum.
I have a vested interest in you being able to self custody your coins.

I may one day wish to transact with you using a peer to peer electronic cash system without going through a financial institution.
I'll need all of you as self sovereign as possible.
2023. It's time.
If you have nothing to offer the world, it's time to start thinking about it.
Personal experience selling a product
I've had success stacking bitcoin from selling pre-built Bitcoin Nodes over at the Ministry of Nodes store, which I started doing in May 2023. Over that time, many have customers have paid in bitcoin using both lightning and on-chain. The value of the bitcoin has increased significantly in that period. When I first started, I'd get well over 1m sats for a Nodebox. Now I'm getting under 300k sats.

Splitting bills
Another way to acquire bitcoin is through splitting bills. If you can convince people to pay you back in bitcoin for their bill that you've paid in fiat, this is a great way to swap your dirty fiat for bitcoin. This can work for hotels & accommodation, restaurants, group outings etc.
Conclusion
I'd encourage you to participate in the bitcoin peer to peer economy as best as you can. There are many who are at a stage where they'd just pay in bitcoin rather than go through a fiat financial institution.
