Then Fatmans proposal on terra money would be the best shot. Basically everyone would get UST maginal tier based back in form of USDC, favoring smaller wallets. Example: The fist 5000 UST would get 90 percent back, the next 15000 UST would get 80 percent back, the next 25000 UST would get 70 back etc.
So some who holds 40000 UST would get back: 5000*0,9 + 15000*0,8*20000*0,7=30500 USDC.
Above is just an example not real numbers.
I did read fatman proposal but consider about the LFG reserved that still left in the wallet and is it possible to do this? I think that it's not even possible. LFG has only small reserved funds for now. Refunding even when fatman called that as small users are not possible anymore with these funds.
Bitcoin already gone to bought UST and LUNA. The current buyers of LUNA and UST will be also complaining about this too. ]
This is a very hard time to decide which way that will be used to fix this problem, this is the fault of foundation. People have been expecting the fatman proposal to be accepted before LFG become transparent and told public about the truth of fund left on its hotwallet.
