For those that think Bitcoin and sidechains (pegged Bitcoin) will cause market cap of all altcoins to go to 0, do you also think that all countries should adopt the USD or peg their currency to USD?
* And that is why I work for Coinbase.
I don't see what point you are trying to make with your USD analogy. Fiat is a source of wealth for governments (printing money doesn't increase a countries wealth, but it increases the printers portion of the pie). Now why would China for example want to give the United States the ability to constantly decrease China's portion of the pie?
I've said it before and I'll say it again, why create entire new coins/distributions for every new idea/feature/use (micro/merchant transactions, smart contracts/properties, anonymous transactions, etc), when those features could simply be built upon Bitcoin's rock solid system/distribution?
