ELI5: UST held in CEXs?

Sorry if this has been answered before but I’ve been struggling to find this information in the Revival Plan 2 proposal and other proposals and I’m sure I’m not the only one wondering about this.
What should we expect if we held/currently hold UST in Nexo, Gemini, OKex, etc? I understand it’s going to be very difficult to account for all of us so should we try to move it to a Terra wallet or just keep holding it where we have it?

DK said he will airdrop them but I would say move them out to Terrastation. It’s not clear how many CEXes will support the new luna.

For once the pre-attack snapshot includes only aUST and not UST. The post attack snapshot does include normal UST, but it’s so worthless now that I expect people to buy cheap UST right before the launch

now ust/luna ratio ust gives more new luna if you compare 100ust 100 luna worth why you say worthless?
