Hahaha! One does not simply do that. But since you said that you've already done that, can you teach me how to print my own USD notes and strategies on how to dump them?
Very simple. you take a piece of paper and write "$1 million monopoly dollars" on it. Then you go on the internet and create a bunch of shill accounts and start shilling the fuck out of your monopoly dollars. Then you go around to local businesses and continuously nag them to accept monopoly dollars as payment. Because your monopoly USD has the same fundamentals as USD and is interchangeable 1 on 1, you will essentially double the money supply of the real USD, just like the OP proved in this very informative and useful thread.
By the way, this technique works with anything. I made my own "better version" of gold recently and tripled the supply of gold.
