Do you think Bitcoin will become the reserve currency of the world sometime in the future?
No, I don't think Bitcoin will become the world's reserve currency. Because there have many facts of course. Bitcoin is popular but not enough familiar with every people of the world. Bitcoin has volatility nature, anytime its price can go very high or low, no one has bitcoin's control. Bitcoin is not helpful for the developing country because its tax-free, World has better currency than Bitcoin. So, bitcoin can't be the reserve currency of the world.
Since most altcoins in the market today, are dependent on Bitcoin's price movements,
I agree with it, without bitcoin's good movements, altcoin will not be big! Bitcoin dominate the crypto market, that is why many people know the cryptocurrency market only for Bitcoin.
