Not just because they are a bearer asset but because their scarcity retains purchasing power orders of magnitude better than paper money.
Bitcoin retains purchasing power? Better than money?
Can you explain? In what real-world scenario does Bitcoin have stable purchasing power?
Bitcoin market price tanked from 54k to 29k a few weeks ago, and currently is still around 30k.
That's not exactly what I would call retaining purchasing power.
No, not really. In fact, today it's still lingering around 32k.
Regardless, it seems you inadvertedly tried to make the case that indeed Bitcoin is highly volatile and does not work at all as a store of value.
