some aspects of your plan look interesting,
but i still don't see how a 10% ICO,
followed by giving away 89% (with 25% of that going to dev fund) will expect to maintain price.
although i expect ICO participants will naturally earn more in regular payouts?
Check out FAQ #5. That may help explain things better.
http://silvercoin.io/faq/The 25% going to the Dev fund is part of the level II SilverPlan membership structure, but that is completely optional.
100% of the 89m coins will be distributed via the level I affiliate plan. Nothing goes to the Dev fund from this.
