Captainhook, your upcoming tweaks look perfect to me, but i think it would be an error not to consider POS (not much 3% a year would be enough to make more people tend to hold) for this great coin. I mean, great name, premine gone through ipo, x11 algo + pos hype (see blackcoin and all clones crazyness), icoin would fly within days and be massively adopted. Icoin would be the first x11 POW/POS coin. All blackcoin clones around are still running on old scrypt during pow phase.
Also, the 500 millions total coins is misleading i guess in people's mind. This coin is rare, only 10 millions right now !!! And will be even more after ur tweaks !!! It should be more clear in OP i think for people to make up a target price more easily as most of them don't know mining is supposed to last decades as a very slow release rate.
I'm glad icoin will be faster and even more scarce.
Well, u know what u have to do to make it one of the best coin around specs wise. Icoin future is in your hands Marketing will be a piece of cake after that, easy to promote a well thought coin with flawless technical side.
Can't wait to finally see icoin rise and get its shiny coinkite one day !
Add these modifications with the IPO suggestions I made above and I think you'll have a winner.
The next thing to consider would be the coin release schedule during the PoW phase and how long it would last. I recommend a 1-2 year mining period while x11 is still asic resistant.
