How is anyone allowed to make their own USD (or any forms of fiat for that matter) of any currency?
Is there a method for doing this?
Couldn't i just create a ERC-20 token and mint myself 1B tokens and use that to buy up the coins in circulation if i wanted to?
How would you get it on exchanges or let people use it as a USD Pair?
There is no special method to doing this, what matters is creating value.
The etherum blockchain is open to you if you want to create your erc -20 tokens, But who will buy from you ?
You need to drive a value, drive a purpose that such token will serve in the world.
Thats the only thing that can attract investors and quality exchange platforms.
Always dyor too
Other than that, its a childs play
