I also can't find any details about these 10 countries. I've been looking at their telegram, web, medium, even reviews on their app on google play, and the closest mention was their partnership with "rupiah stable coin", which means one of the country is Indonesia. One down, nine to go.
Interestingly, for an app that's being used by 10 countries, their app were only downloaded by 1,000+ users. This number is certainly very low if we compare them with the claim of 10 countries. Hopefully that's not just a clickbait
Lol, this is just a digital currency wallet like any other wallet we have on play store, anyone from any part of the world who have access to play store can download it, that doesn't mean there is a serious and established or should I say approved usage of it in this countries, perhaps if only 1000+ members have download so far it means only few people out of the 10 countries have download the wallet,
Between we have several wallet app this days to make a choice depending on what we find interesting about the app, to me I don't see why I can use this app since there are many similar with good service and with a good track record as well out there.
