Ok.. great to know all this stuff...
So for arguments sake, lets assume premine and its being distributed at a controlled and equal amount with limits on quantity.
Would this stop or slow down the premined coins volatility when these misleading articles about countries banning coin are made?
When China made an announcement, it had am impact on the coins price, so someone in the USA was directly effected by what China does or does not do. And why China? Is it due to them having the bigger mining rigs, that meant that more coin was in circulation in China?
Consider a premine, somehow cleverly distributed evenly amongst all those with internet access. (which is "unfair" globally, but that's another issue).
The moment that premine hits their wallet then what's it worth?
It's initial price would be 100% speculation, their would be no existing utility to anchor it to the "real world".
One might create an exchange for fiat or other coin, to see where buyers meet sellers, the market would be purely speculative.
In a 100% speculative state, a coin is most vulnerable to misinformation, misinformation spooks the mind that speculates. So at the moment of complete premine broadcast it would be at its most vulnerable.
It makes more sense to have a coin evolve slowly, gaining utility at a rate proportional to network growth. The utility can be thought of as a floor underneath the volatile speculative price chart. I'm not sure on the utility/speculation ratio for BTC at the moment but it's significant.
Free market is very similar to genetic evolution, to think one can shortcut evolution is short sighted, the optimal solution can not be created. It must grow and find it's path naturally, otherwise it WILL be put on the wrong path. Bitcoin will still undergo alot of evolution before last mined coin, the idea of trusting Bitcoin is slowly growing in peoples minds.
I would go so far as saying: If one wanted to ensure the success of a premined coin, then ALOT of centralisation and HARD control of users would be needed, because as you allude to, you would be battling for the minds of the users against large entities. Perhaps the only organisations that could successfully launch and run premines would be governments or massive corporations.
