To answer your first question, the token price and your total value of SafeMoon is a reflection (no pun intended) of the exchange where you bought your coins from. There is no central exchange at the moment and each exchange sets their own prices for the token. They're generally pretty close to each other but rarely are they ever the exact same price. One of the reasons for the consolidation is to create a more stable token, which should effect the varying prices to some degree as well... Especially once the price goes high enough so that the differences between exchanges are more noticeable.
To answer your second question, there isn't really such a thing as SafeMoon UST. It's just SafeMoon. When this board was first created, I tried to fix the tag but someone kept switching it back. I think they thought that was how the token was going to be listed... but it wasn't. I didn't want to play the back and forth game or irritate The Powers That Be so I eventually left it alone.
