I've been working with cryptocurrency for a long time and because of the excess funds I earn, I allow myself to gamble or buy a premium account in sex chats. Unfortunately, not all resources allow you to pay for your services with cryptocurrency, but many popular sites with pornography or gambling have the function of paying with cryptocurrency. Also in my free time I like to order a girl from an escort Agency, they have a function of paying with bitcoin and they provide complete anonymity of information about you. I think that in 10 years, the normal currency will disappear and only the virtual currency will remain, and it is not necessarily a cryptocurrency. Many countries have almost abandoned paper money.
