My story:
I'm holding KARMA since 2014, was buying it on Mintpal and Cryptsy.
I couldn't sync a wallet in 2015 that's why I asked bitwho to return coins from Mintpal directly to my account on exchange,
thanks to him.
Now all my coins are stuck on Yobit (their KARMA wallet is in maintenance for months) and their KARMA market has zero activity, it's impossible to sell coins or to transfer them.

The KARMA swap was announced in the OP: you were able to swap old coins 1:1 at the beginning of November, 0.6:1 currently, only 0.08(!):1 after January,18.
That means that when Yobit finally enables KARMA withdrawals (obviously not in 2016), people who have KARMA on Yobit in better case will receive only 8 percent of their coins... Either people who don't check the announcements regularly.

The Cryptopia exchange stopped old KARMA trading, it will be replaced with KTN.
So there is no even single chance for old investors who have coins stuck on Yobit (and the old coin is going to be delisted and replaced with the new one):

they will not be able to join all things you announce and they will lose all their coins (not literally, but they will have them inactive and stuck on old abandoned chain with no listing on exchanges, which is pretty the same) after holding them for years.

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.
