Thanks for your comments Ragnarly.
I have some low IQ questions: The new alt-coins are given away at first. You can claim as many of them as you want, up to the number of bitcoins you have.
You are automatically allotted the same % of the alt coin pre-mine as your % ownership of bitcoin, at the time of nucleus formation. No one but the controller of the bitcoin private keys can claim the pre-mine. Even if you do nothing, you still remain a "holder" by default.
At the beginning, the alt-coin has almost zero value. If the alt-coin gains users, you profit by trading the alt-coin for Bitcoin? And/or a different alt-coin?
Let's say the alt-coin launches and is trading at 0.01% of the bitcoin market cap. Most people will just do nothing. If the alt ever takes off, these people sleep soundly knowing that they own the same % in this new alt as they do in bitcoin.
Now some people might say: "wow, NxT is trading at 0.4% of the bitcoin market cap, and this new alt is better because it has a more efficient coin distribution and a broader potential user base. I think I'll buy some more of this alt coin."
Others will say: "this is stupid. I'll just dump all this "free money" and then gamble my 0.1 mBTC at just-dice.com"
If more people decide to buy, the price will rise. If more people decide to sell, the price will fall.
What incentive would someone have to create an alt-coin, if they have no competitive advantage in getting them (Apart from their Bitcoin holdings)? Or in other words, why would someone go to all the work of creating an alt-coin rather than wait for someone else to do it and then claim the alt-coin?
It will be difficult to profit from what are known as "scam coins" and "pump and dumps," however, if you have a genuine innovation that is actually useful you will be rewarded by natural market mechanisms.
When your coin launches, it may trade at 0.01% of the bitcoin market cap. You can buy 10,000 of your alt coins for 1 BTC. If you continue to develop your alt, and if people begin to agree that it is useful, your 10,000 alt coins will be worth more than 1 BTC (possibly a lot more).
This proposed distribution method allows bitcoin holders to piggyback innovations in cryptocurrency, while still rewarding alt-coin developers for genuine innovation.
