It isn't about words, it is about the mindset.

To me, Bitcoin is a savings mechanism, which is, by definition, where I store my surplus energy.

After I spent all the money needed to improve my house, after I bought even more land, after I stocked on food, after I bought all the gadgets I want, after I traveled ...

It ain't much, but it is saving steadily.

You can't "save" by cutting out necessities. That isn't saving.

Now, if you don't truly enjoy your current home, and you think you will benefit from an upgrade 5 years later thanks to BTC price, sure, that is a very different story, and probably a good strategy. But it isn't investing, or saving...
