People in countries with shady governments and broken economies have higher likeliness of using Bitcoin and stablecoins. Most countries are simply in not that bad of a situation so they think they don't have the need to use them.
It is easier advocating for adoption and preaching adoption to people in the countries where there are broken economies and things are difficult because once you highlight that Bitcoin has the ability and prospects to change their financial situation they suddenly become interested, in other countries where the situation is not so bad, you need to explore all the benefits that Bitcoin holds to someone that you're trying to talk into considering bitcoins because they may not be interested only if you tell them that it can change their financial situation since they are not doing so bad, but if you can list out and really explain the other benefits it is possible that one would be attractive to these people.
