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?
No, I don't think so. We have different governments (and laws) running each of our countries and there is no way they're gonna let a single currency to be used as mode of payment, much less a decentralized one which they cannot control. They can regulate it but I don't see it becoming a universal currency to replace all of fiat currencies around the world. The government will rather make their own cryptocurrency if that will be the case.
