Certainly you cannot solve the Yobit issues, but it's not the point, the point is why not to leave the swap rate 1:1 for old KARMA investors who have no chance to join the swap since its beginning due to exchange issues. That would be fair.
Another thing that is not fair: many old investors are long term investors and many of them don't read your announcements regularly, but they faithfully hold coins for years, they were buying KARMA because they believed in the KARMA future, because they trusted people behind it; give them a chance to swap their coins in 2017 for normal rate, maybe not 1:1, but 0.8:1 or so, that would be really fair.
well, it's a good test for me, whether new karmacoin (or token) is a scam or not, let's see how they decide
in a pretty similar case of new 42 coin (that's not a token though) there are:
a) a swap rate is 1:1 for the whole swap period
b) coins are sent to the burn address
c) better to quote a dev of 42:
I will let the people to swap after the January, 2017, if their old coins were not touched after the block #1990382 and we will have remaining the new coins.
42 has their own case. We can only promise to do what we said we'd do and not to do what OTHER altcoin/s or DEV said they would do.
