Do not send new Luna automatically to all post-attack Luna and UST holders. To get new Luna they should send their old Luna/UST to the burning address.
Part of the community (including Do Kwan and majority of the team) wants fork. Another part (including the majority of regular people) wants to keep old Luna reducing its supply. My suggestion is a reasonable compromise between these two positions. If it would be approved everyone could decide which way to go for him/herself.
Make changes in chapter Token Distribution of the Terra Ecosystem Revival Plan 2 [AMENDED]
Allocate 25% of new LUNA for post-attack LUNA and UST holders.
To get new LUNA people should send their old LUNA or UST to the LUNA’s burning address terra1sk06e3dyexuq4shw77y3dsv480xv42mq73anxu
Immediately after it they receive new LUNA with a rate 1 new LUNA for each 50.000 old LUNA sent to the burning address, 1 new LUNA for each 100 UST sent to the burning address.
30% of these new LUNAs are unlocked; 70% vested over 2 years thereafter with 6 month cliff.
All old LUNAs and USTs sent to the burning address are immediately burnt.
Thus each person would be able to choose: either to swap his/her old LUNA to the new one, or to keep old LUNA with dramatically reducing supply, or to swap part of his/her old LUNA to the new one and to keep other part. Therefore everyone will be happy!
