What difference between aUST and UST

anyone please clearify me.

if I earn/staking UST at binance do I still count as aUST or not?
I have 22k UST staking in binance do I got a 1 option (Pre-attack aUST holder) ??

*1. Pre-attack aUST holders: 10%

  • 500K whale cap - covers up to 99.7% of all holders but only 26.72% of aUST
  • 15% unlocked at genesis; 85% vested over 2 years thereafter with 6 month cliff
    *2. Post-attack UST holders: 20%
  • 15% unlocked at genesis; 85% vested over 2 years thereafter with 6 month cliff

Thanks in advance
