I answered a few more times, so you can have a look at one of the articles above, specifically at this one: https://steemit.com/steemit/@dragosroua/how-sbds-are-created-and-what-could-happen-if-sbd-is-pegged-to-usd10-instead-of-usd1 it's a bit more complicated than just a few lines in a reply, but hopefully it will give you a better understanding. Thanks for your support!
