fiat-minded, profit-driven approach?
Everyone has internal meanings for things they say and often they do not align with what others mean by the same words.
To me fiat minded and profit driven are not both bad. I work and run a business to make a profit on my time. I save in Bitcoin because I don't want that work to be wasted away. I want my life force to at least sustain and better yet increase. That's called profit. It's not fiat minded.
Now, fiat minded is primarily a thing produced by monetary inflation. If your money is ever decreasing in spending power we are incentivized to spend now and not save. Its time preference. Fiat influences us to spend rather than save. Its different from profit minded.
A bit of advice. You really should not care what so called maxi think. What do you think? What are your goals? Many that call themselves Maxis are just LARPers and keyboard warriors.
You clearly see the tradeoff differences in a stock vs bitcoin. The rational advice many give on MSTR even from Saylor is buy Bitcoin. If you have money in a tax advantaged investment account it's likely going to be a tax hit to pull it out. Maybe you think it's worth taking it out for many reasons. No one should be able to make that decision for you. Depends to much on your view of government and the future.
I would never buy MSTR over bitcoin. But if I had money trapped in a fiat based system and was going to lose a lot by pulling out I would need to do the math. If I decided to leave it in I would probably buy an ETF and maybe MSTR. Good luck
