In my country you can pay bills using either BTC, ETH ad BCH. Your earnings can be used as a payment equivalent to your billing balance plus rebate. This is such a useful application and I can do freely anything about it. You can also but load, or pay merchants like credit cards all using your crypto balance.
not every country can boast of such an opportunity to pay for services and goods...
Yes, like in the country where I live and I have not found a purchase using Crypto and although there I have not tried it.
and until now I have only exchanged Crypto for currency in the country where I live so that I can use it for real purchases, and what I do is more convenient like that and not all countries can do it like that.
