I've been buying, and mining Karma, since the launch.
But that's correct, to keep my coins, and get 1x KarmaShares, as advertised.
You know that you can still buy Karma at 1.75x (not sure for how long...) right?
So what about spending half of your Karma in Karmashares?
You probably will get more dividends from Karmashares if you spend half of your coins in shares, than by keeping the coins at a 1:1 Karma/Karmashares ratio (because the exchanges could take the most part).
Even if you only think about what is best for you, the 1x Karmashares model is not good.
