Do you guys billieve that bitcoin will become the only one currency that can use as a mode of payment in the whole world? How is this become posible in the future?
I doubt that. Althrough we use Bitcoin to buy pretty much any other coin, I think Bitcoin is by far the favorite candidate when it comes to global usability. There are other coins that deserve that spot.
At least all the world will come to one platform, they will use bitcoin globally, although so many other altcoins will also be there, but still bitcoin will remain as number one and for all the people bitcoin will be the first choice to use for different purposes.
I don't think there will ever be a global consensus on bitcoin and it's network because we almost wake up everyday to meet one fork or the other and many are doing their own thing instead of supporting the core devs and so these differences makes it difficult for the entire world to settle on bitcoin as their currency.
