I completely agree that crypto will be the currency of the future. Cryptocurrencies are already used all over the world and constantly more and more countries begin to legalize cryptocurrencies and recognize them as official currencies, this is just a matter of time when the whole world will already fully begin to use cryptocurrencies with its full potential.
Cryptocurrency is not the currency of the future, it has long been the currency of the present. I pay through bitcoin and other cryptocurrencies for almost all services that I need during the day. Yes, I can't pay in the store yet, but for example, you can pay for an apartment with cryptocurrency for a long time, and this is great.
I find that had to believe that you make purchase of almost all services you need during the day with btc and someone can pay for an apartment using btc, if this is true then it is really great to know, I also think crypto will be the preferred currency, maybe the currency won't be btc but some other cryptocurrency with very little transaction fee cost.
