No, I do not believe that in the future a single cryptocurrency will dominate the world trade and finance because that would imply a type of centralization that is not convenient for anyone. However, I believe that in the long term only very few cryptocurrencies will be needed to cover the world's economic needs, just as currently only very few fiat currencies are needed to satisfy world trade (dollar, euro, yen, etc.). In addition, we must take into account that the tokenization of the economy is already underway, so countless tokens will be emerging in the coming years.
