Well I have been thinking of this possibility of expansion of Bitcoins use to such an extent that one may simply travel with hands in one's pockets! That should be level at which the ascendance of cryptocurrency should be and towards which we as a community should work.
The very fact of travelling will include more than one fields of business into its fold. Flights, eateries, pharmacies, hotels, rooms, restaurants, shopping stores, movie theatres, book stores, gyms and fitness centres, taxis and buses. This is not just a dream but a goal that we should try to reach.
I am not necessarily promoting a cashless & cardless society but cash & cards can simply be an alternative. All you may need with you is your cell phone and ID card to move all around the world. Into such a morning of sun shine, I am looking at. But gradually what turns out is such a cashless and cardless society with eases lives.
The world has become more and more cohesive and smaller. Getting knitted closely together. Like the evolution of species, cryptocurrency has evolved from various different ideas to a superior manifestation. And today though slowly but steadily we are finding the shift towards it. It is in near future that we may find the world being defined by whole new parameters of currency, economy and development to which cryptocurrency and especially bitcoin will be an integral part.
Honestly, I really do think that this is such a good idea/dream since I too have been wishing for this to happen without having to be forced to choose sides whether go all cashless/crypto or just fiat alone. it would be really nice to be free to decide what we really want to use in our everyday lives. But the sad thing is reality just won't allow this to happen. there are just too many things that are involved that clearly hinders this kind of situation from really happening in real life. The biggest problem is the banks and governments, then there's the availability of internet for all people. The fees, the confirmations time frames, and so much more.
But still, I am really not losing hope that someday this will really happen. although i may not be able to reach that moment, I still want to believe that it will really happen.
