You make some interest points. "Developed Nations" across the globe are facing declining birth rates. There are a multitude of factors, none of which include natural biological decline. To your point -- it's the difference between those who "have" and those who "have not". These days reproduction is seen as a financial risk / burden.

Without knowing the percentage of population that owns liquid cryptocurrency to be used as disposable income is questionable. Cryptocurrency is a speculative asset as a whole, but the inherent value remains strong specially tied to instutional investments. Which is to say that I believe the majority of cryptocurrency owners would rather hold onto their crypto with anticipation it will increase in value relative to fiat versus spend it on a slice of pizza.

A different idea with the parameters of cryptocurrency: a currency exchange. Imagine you partner with a "Cash for Gold" store and give the opportunity for💯

A) Customers to get an easy entry point into crypto, especially an aging population
B) An opportunity to sell physical assets at one store to use next door at your store.. an aging population may not have disposable income, but im betting they have physical assets that can be sold into an investment
C) Better margins and not dealing with non-durable inventory.

I don't want to dissuade you, but rather "food" for thought.
