Living without cash could be something very useful for us. Imagine traveling everywhere you want with the unique crypto coin, bitcoin. It would be awesome
Yeah in some scenario using cryptocurrency in daily living is cool but if we are going to use certain alts or btc that requires transaction fee on every move that would not be practical I think. Imagine buying a 0.50$ candy and you need to pay the 4$ trasaction fee..lol
Indeed, we can not use cryptocurrency on every items we want. And due to the transaction fees and the confirmation time that sometimes takes too long, crypto will not make real money disappear.
Do you mean instant payment with cryptocurrency? Do you know Ripple? It is one of coin can provide the fastest service for global transfer money in cryptocurrency at the moment. I do not know the future, but I predict the government will need to use the technology from this currency to build a new blockchain coin if they want.
