That's where you're wrong. The seed of the crypto garden that was bitcoin will be a relic, within the next 2-5 years. The very idea of decentralization cannot be upheld by one single currency. It's the very definition of centralization. There needs to be a plethora of valid cryptos with different usecases that compete and evolve through said competition.  Bitcoin cannot be the only currency of the internet, just like we can't have the dollar the sole currency of the world.
