I think it would make the most sense to have the distribution be ongoing, in a similar way to Bitcoin distribution, with regularly halvenings.
* The first 10 million wagered CLAMs claimed get 1 DC each.
* The 2nd 10 million wagered CLAMs claimed get 0.5 DC each.
* The 3rd 10 million wagered CLAMs claimed get 0.25 DC each.
* And so on.
That way you have a known fixed money supply of 20 million DC, you incentivize people to claim earlier rather than later, and you have an ongoing supply to keep people interested. You just pre-mine 20 million DC, keep most of them in a well-known "unclaimed" address, then everyone can see how many are still to be claimed.
that is a great idea dooglus
