Of course. Its current price growth is spurred by previous price growth, not actual use. Its use cannot grow since its blocks are full and its fees are prohibitively high. Bitcoin maximalists have resorted to the preposterous argument of Bitcoin as a digital store of value when, by definition, that's not how stores of value work. You can't just proclaim yourself one, it's built on a history of purchasing power stability.

The reason for the purchase is a weak rationalization, the expectation of further price increases necessitates a bubble. Textbook irrational exuberance.
