President Richard Nixon’s actions in 1971 is end dollar convertibility to gold. After US every country in the world did same thing to their currencies. That's mean the value of money in so unstable and the fucking government can print unlimited amount of money which all of us know can lead the economy to complete break down. But bitcoin is hole another thing. It has real value because of 2 important factors: 1-No body can control it specially governments. 2-it produce by mining process and you can't just making a ridiculous amount of it. I just hope billionaires and governments don't destroy it.
