This is what is happening to the US dollar ^^

The petro dollar is indeed becoming unnecessary and it looks like especially China is starting to show its influence on the global market. However I do have my doubts that they will ever succeed making a centralized crypto successful, but we should keep our eyes open! Unless people are staying in oblivious ignorance...we're gonna have some great times ahead of us. With what the blockchain is able to provide for us the whole infrastructure is gonna change, exciting times :D!!
