CZ is helping the Terra team and providing ideas on how they can recover the Luna and UST and I think maybe Do Kwon is still brainstorming or checking for the best proposal to recover the loss with their team.
Maybe the community will agree more with the solution from CZ compared to the issue of the new coin proposal v2 because it will be difficult to generate new coins, even though there is an initial increase but it is not guaranteed to be trusted again for long-term investment. Based on experience from other altcoin projects which are very vulnerable to drama from hacking and dump issues, so the main solution is replacing new coins but it won't work until the project dies. So anyway they have to solve the problem on the old coin and the proper step is to consider the solution from CZ.
