I think it will help, if they do.
True, wie don't know what the future costs are, but that would matter more if the conversion will be linear, which I doubt.
The more EDC you have today, the more you suffer diminishing returns I believe. Up to a point where you run into a wall of cap.
That's how they handled things a year ago.
So it could be my current 60 EDC get me still 60 Marks, but at 100 EDC I would only get 90 Marks. At 500 I might only get 250 and every other EDC I might have is simply gone...
So knowing this would very much help me decide, if I better spend what I have know or if I am good keeping it.
