The article I linked to was from ABC news (as mainstream a news source as you could find).
How is this propaganda? You're saying people in countries with hyperinflated currency have no use for crypto and don't use it? Can you back this up? Can you explain why there are significant premiums for Bitcoin when buying from exchanges from these countries? Or is this propaganda too?
Of course there isn't data (except of course from the exchange rates). These people are breaking the law and at risk of death or imprisonment. What type of evidence would satisfy you?
