Yes I also think that bitcoin is becoming a worldwide currency and more people are interested to know about it, how they can treat it.
I dont think so, since bitcoin is a digital currency, every people in this must have Internet connection and gadgets as well if that happened. So I think it is not a good idea that paper money will be xtiynct just think about the people who dont have and still can run with techy world.
I think no matter the number of bitcoin users in the world, when you can use bitcoin wherever you are even though it needs gadgets and internet to access it, I think it's included in the global currency, because you can use bitcoins anywhere and in all countries, and you can also send Bitcoin anywhere to all countries in the world?
In terms of usage it is really globally but in the number of users, it's only few to get into it unlike USD that are use by many. Though the importance of btc is really increasing for its user that anytime soon it will be popular thrice it is now.
yes as of now we are still few if you compared to the total population but fortunately everyday users are increasing rapidly on the contrary, methods on where to use it is not.
most cryptocoins are mainly used in trading/exchange platforms and theres nothing bad about it. its just that since they are still money after all. the users should have a variety
of choices on where to spend it, unfortunately its progress on that is really slow.
