Yes that's true bitcoin is getting more and more popular, and many other altcoin still depends on bitcoin a lot. Maybe because it's the first coin and it's not really easy to replace the first, moreover if the first is successful. But maybe other altcoin will have other chance later in the future. Begin to be better and doesn't depend on bitcoin anymore.
But i think although that means bitcoin is the best in cryptocurrency, it doesn't apply in the real world. Since i think usd is still better and it'll be hard to replace usd, although i like bitcoin a lot and i'll be happy if it becomes more popular than before.
Yes. USD being the current reserve currency of the world, would be too hard to replace in the future. I've once thought about Bitcoin becoming the reserve currency of the world, because of its increasing popularity over the course of time. However, I've found out that it'll be nearly impossible for the pioneer cryptocurrency to achieve said status unless it becomes centralized. Only then, governments and banks around the world could easily manipulate it and enforce AML at will. With Bitcoin's current state, it's impossible to track down every user with the purpose to freeze access to their funds.
This makes it unideal for a reserve currency of the world, unlike the USD which is backed by controlled by the US government. Eventually, as blockchain technology becomes studied by such entity, the USD could change from being a physical currency to being "digital cash". Then, the USD might remain as the reserve currency of the world in the future, or another currency would prevail over the USD.
Nevertheless, what matters is that Bitcoin has become a global currency which anyone could use without restrictions. It may not be the reserve currency of the world, but it's a store of value which has gained the trust of many people in the mainstream world over time. Just my thoughts
