We have decided to go with USD as the default display currency. 90% of our expenses are in HKD and the rest basically in USD with only a tiny amount in other currencies. However, charging in USD is not a problem for us given HKD is pegged to the USD.
But we accept EUR, GBP and CNY too, all of which can be selected from the first page to see pricing in preferred currency.
Any way, Eddie Johnson, you seem to have a rather inflated view of the US. Don't get me wrong, the US is indeed a powerful, creative, productive and innovative country, but it is not the only one and plenty of developed nations out there equal, or even surpass the US on those fronts.
China is the only threat to the American dollar but this threat is very limited as China is only good at reproducing American Made designs. China lacks the ability to innovate anything, for instance name one thing that China has invented other than fireworks and Chinese Food. Lack of innovation is likely why China's GDP is less than half of the United States GDP for 2012.
Although most well known Chinese inventions/innovations are quite literally ancient, innovation still exist today. You could probably see most of China's innovation in the form of manufacturing techniques and material synthesis. For example, the Bird's Nest stadium built for the Olympics used large amounts of a metal alloy that was 'invented' locally, which was critical in the construction of the whole building. Not that it's a great example.
But I ask you, what major inventions/innovations came out of the US that are well known, world famous and modern.
America could easily re-gear itself within two years to use robotic engineering to rival gross domestic exports of Germany and China if the need were to arise (such as if America were to go to war with China). But this isn't likely going to happen as we don't mind paying the Chinese to make our nail clippers, pencils, and other cheap products as we have far greater things to do with our time
If this were true, then why do they not do it? Probably because it would cost more money than it is worth. The American economy is dependant on cheap Chinese labor.
if China were to go to war with us we'd surely win as our much smaller population collectively is far smarter, faster, stronger then the sum of their people.
You have got to be joking. On what do you base this claim? No doubt there are many smart people in the US, but I hardly believe that the majority are 'smart'. There is little evidence to support such a claim. In any case, a war between USA and China would result in NO winners. Both countries posses sufficient nuclear weapons to wipe out the world many times over.
The only thing that will replace the USD on the world market is if the USD were to join the EU (not likely at all) and/or a virtual worldwide currency such as BitCoin (cool thought but not likely to happen anytime soon) were to replace all currencies.
The USD will be an important currency for many years to come but the Euro and other currencies are quickly taking over the role from the USD as a reserve currency. The Euro is already the 2nd most traded currency, being the 2nd most 'reserved' currency and has the most currency in circulation.
As a whole, the EU is the largest economy, and probably has the most amount of technological innovations of any other comparable economic area. It has a highly skilled and highly educated work force, high wealth and high level of development. It produces huge amount of high tech products and has well developed infrastructure. As a whole, it exceeds the US by about a trillion dollars per year in terms of GDP.
Again, I am not saying that the US isn't a wealthy and innovative place but it is not exactly far ahead of their international rivals. China included.
