People will realize the importance of it, when they're going to need it. If you're in a country that's currently economically fine, it's very easy to ignore bitcoin. For the Venezuelans and Zimbabweans though? Chances are, you wouldn't even need to discuss the technicals of bitcoin for them to be interested in it. All they need to know that it's unconfiscatable, decentralized, easily tradable and sendable, and that it's deflationary. Those characteristics itself would be attractive enough for them to hold/earn bitcoin because the country they're in is economically broken.
