It is fail because there is basically an endless amount of coins being mined, because the more miners - the more coins there will be. So it doesn't matter if you start mine now or in two months, you should always get the same amount with your hashrate. While this may seem 'fair', on second thought you may realize this is not the solution, as there is no scarcity.
And without scarcity the coin will have no value.
You absolutely wouldn't, the block reward constantly decreases
relaunch your coin, it was a good idea.
just get a p2pool ready that will hold and collect 10% that will be your reward i think is fair too so no need to mine on your netbooks or whatever 10% of a good strong p2p on the first days will bring in a ton of coins.
and get a pro to compile the windows exe
get help with both those things if you need, i would ask blastbob to help you with the p2pool and also he seems to be someone that most trust and will not premine. I am sure he can compile the windows thing too for you.
then release again asap before another coin just uses your idea.
releasing with working p2pool will be awesome.
