I go on #2 option,...
Pay the deposits and remain unpaid those who are not cover.
30btc can pay a lot from the pending deposits.
From doing that ,thise paid members still deposit again nd then use it to pay the other remaining.
Instead of giving us all 5% which is too much unfair for high rollers that paid older investment fairly.
If I understood what you said I agree with you. Do not pay me, I only invested 0,001 BTC, this is a bit of dust. Pay the big depositors instead of the small ones. Someone can lose 10$ but 1000$ is harder to accept.
