will gold be outdated by fiat? This is the kind of question we ask ourselves when we compare something we don't fully understand, to something meant to coexist. Outdating is a complex arguement, because everything has a time and place to be the flavor.

What btc will provide, will not become outdated. The other currencies looking to expand on its origin would have to be valued for the percentage of innovation and then compared to the creation of the cryptocurrency in the first place. Its like giving credit for good genes. Satoshi took things from different projects, and made one product providing all the things they tried to deliver. Sure, some one will come along at the right time, and say, hey this is missing this, that is missing those, and solve. Still the amount of time since btc creation, and what it provided for 8 years without any real competition, makes the probability of there being an aspect to solve that would catapult a currency to stardom, less and less about what separates the coins, and more about compatibility and agnosticism.
