Yawn, another alternate currency. These can be attractive to facilitate barter, so individuals can avoid taxation, but are more likely to involve fraud.
Some would argue that modern official (fiat) currencies are not free of funny business. After the US dollar was decoupled from a gold standard it has inflated (lost value) a bunch.
The main difference these days as the would economies get more closely coupled, every central bank is pedaling as fast as they can, to stay in the same place (I'm sure there's an Alice in Wonderland joke there somewhere). In the past a country could win a relative export advantage by devaluing their currency, but if every country does it at the same time it mostly nets out to no change.
The central banks have a somewhat justified fear of deflation... The classic argument from central bankers is "we know how to fix inflation (raise interest rates), but we do not know how to fix deflation" (like japan in the '90s). So inflation is the lesser evil. I don't trust government to resist the temptation to inflate their way out of the current debt burden all of the western nations are struggling with, allowing them to pay back debt with cheaper currency, so this needs to be watched.
If you want to really piss off China try that. It could be worth them going to war over. Right now China is playing games with Japan over small islands in the Pacific, but I suspect this is to distract the Chinese public from the coming transition in leadership and weakening export economy. There were recent worker riots at Foxconn (apple/dell vendor) but this may be over reported in the western news. These companies have factory compounds as big as a small (medium) sized town so stuff happens. But worker pay has been going up and some companies are getting squeezed by worker expectations for more increases in the soft global economy.

While I am not a fan of time banks or alternate currency, I would support internet postage for email. Charge 1/100th of cent for email postage (with credit for every email you accept), and the economic viability of spam would go away instantly.
The spam/phishers are getting more brazen... lately I've seen emails claiming to be from the BBB, now that takes cohones. With a mac, I can just hover over the link, and it shows the real internet link address... easier to not click on obviously bogus link addresses.
