...If the developer successfully does this, maybe it can help Luna get a good position. But I still have doubts about it.
Even if Do Kwan succeeds in realizing all his plans, he will not regain the trust of investors in full to the Terra blockchain. After receiving their compensation, investors will sell UST and buy a more reliable stablecoin, for example, such as USDC and BUSD.
After the collapse that happened to Luna, I think it will be very difficult to get investors to believe again in the project because even if the developers from Luna will do something positive that will have a positive impact on Luna's price, it will definitely not work in the near future at least it will probably take some time a bit longer especially now that Luna's coin supply has increased by a large amount.
