It´s hard for me to understand.
But in conclusion, you double the amount of shares. So for each coin there will be an additionally karmashare. So wheather you receive coins for share, or you keep the share, you will have half of all shares/coins. Isn´t it?
So thats´s just an additionally IPO?
1,000 coins are worth 1 point. Points become shares.
During the special period (now through May 10) you will get bonus points of between 250-1,000%. This week it is 1,000% (or 10x)
So if you put in 50,000,000 coins today you would get 500,000 points. The number of points you get do not change. You can see an example from this page: http://karmashares.com/explorer-v01
The number of shares is not doubled. Actually, we will only know the total number of shares at the end of the special period.
I hope this answers your questions some. Please let me know if I didn't understand. Thanks
