Am curious to know, is there some notable app(s) created for whatever purposes which has a premium subscription payment plan for any of its package and accepts or allows crypto or BTC payments for the package?
Unfortunately for most of the application we can't avail the premium subscription with Bitcoin payments. The reason is that most of the applications are available on either Google PlayStore or Apple AppStore and both of those don't really accept Bitcoin payments. The only best way to avail the premium features of those applications with the help of BTC payments is to purchase Apple gift cards or Google Play gift cards with the help of Bitcoin payments. That's the best way to unlock those premium features with the help of Bitcoin payments.
