Why Bitcoin is techincally invincible

The question of bitcoins chance to take over the world and beat all other financial systems isn't a question of if, but when. You see if you truly think about it, bitcoin is invincible. Any person anywhere can make a node and help improve the network with something as simple as a raspberry pi. But other currencies don't have the same decentralized power that bitcoin does and will, like all governments do, fall and burn. And we are already seeing this happen in small countries like Venezuela. If and when the Chinese economy falls, the American economy falls, and other world players see their currency outlive its self, like the euro already is, they too will begin to adopt alternatives. And what better alternative that an untraceable currency that's decentralized and can't ever truly die.
