This happened historically like many apps have their territories where they are most popular, for example, social media or messengers. The same can be applied to currencies, especially if they use a historical name. We started with the Ukrainian name for currency and intention was to gain popularity in a home region then spread, but we never minded to be popular and used worldwide, even changed the name to more friendly for pronunciation    We never wanted to be official national cryptocurrency. We hope stability can bring more adoption as we want to get a niche of exchange currency, through use as a store of value should be quite possible as well - we don't want to completely stop the price rise, just smoothen volatility and will even have deposits on blockchain like similar to us currencies.
