All great points! Though I don't quite agree that the way I described shitcoins applies to fiat. Yes, they all basically have identical qualities, but my point was simply that I only use fiat because I'm forced to use fiat by those who refuse to accept anything else. The moment that lack if choice goes away, I'll gladly pay with sats.
You made an excellent point with your question at the end, though. So, I think it demonstrates that being a Bitcoiner isn't about how much of your wealth is in Bitcoin and/or something else, but it's about 𝘸𝘩𝘺 your wealth is in Bitcoin and/or something else.
For example, I held bcash for a while after the 2017 hardfork, not because I thought bcash had a future or because I was waiting for it to pump so I could sell it for more bitcoin. No, it was simply because I didn't know how to get rid of it! 😂 I sold it as soon as I learned how, and while I was grateful for the extra sats, that wasn't my intent in holding it in the first place. I only held it for a time because the hardfork made it unavoidable! And then I sold it because I believe it's a rotten and immoral project to its core, and I didn't care for whatever price I ended up selling it at.
Likewise, if someone owns Bitcoin and also stock in a company that they really believe in and want to support, or land that they one day want to build a house on, or fiat that they plan to spend on food and bills soon, or anything else, I don't think that makes them any less of a Bitcoiner. But, if they own any of those things and very little bitcoin because they're speculating that those things are safe and Bitcoin is risky, then they're ultimately bearish on Bitcoin, and are therefore not what I would call a Bitcoiner. The same goes for if they only hold a crypto out of speculation and diversification, hoping to dump on others later to get more sats.
So, all these ramblings of mine (thanks for reading it all, by the way) are to say that we really can't determine whether someone is a Bitcoiner or not based on external characteristics like what they hold in their portfolio. It's entirely a personal matter of one's heart and intentions for what they own, and since it's impossible to know exactly what's in someone's heart, I think it's wrong for any of us to judge anyone based alone on what they own.
