Without announcements ahead of time and precompiled wallets, you are actually reducing the decentralization.

Small miners, who mostly use windows on their home pcs in their free time, and people without IT knowledge to compile things on their own just cannot start mining. Therefore people with the knowledge get a major headstart.

0.1% premine seems fair, but please make the start as smooth as possible for most people. You might even want to contact pool operators ahead of time and ask if they can provide a pool at start.

With just a little work you can do so much better.


Apart from that: What is your coin intended for? Does it do anything significantly better than others? Is there any special use bound to it?
