Hello,
First of all, there is a serious trend towards Luna on Earth right now. The name Terra is better known for Luna than UST. As you said, Terra is bigger than UST. Luna is the collateral of the UST unit. When you apply for a place or open a company, if your collateral is bad, they will not approve of your work. What you have to do here is to stop the UST-related transactions for a certain period of time, then take the LUNA from the bottom and bring it up. After this process, if you make an announcement to the community as “I burned what I bought”, you will ensure the continuation of people’s trust in Terra. When this trust is established, Luna returns to its old days. If Luna gets back to its old days (I’m sure it will.), UST will have better solid collateral than old days.
When I examine the shares on social media, the thought I mentioned above is generally dominant. A Fork or a different action that you will do outside of this thought will not give Terra confidence again. I hope you care about my thoughts and the thoughts of people who trust you.
I wish you good work
