It is a safe bet to dump your green tickets into speculation because, while the speculation may work out, you know for a fact that those tickets are going to depreciate.
Green tickets are almost guaranteed to depreciate, but probably very slowly. Speculation can result in very fast and large losses. There is no such thing as a safe bet.
Probably? We see a lot of examples where they depreciate quite quickly, both in American history and worldwide more recently. Look at a JPYUSD chart, or ask a Japanese guy. Whoa Nelly, that's a steep drop from 2012.
I agree that there are risks in absolutely everything. What's important is to understand and manage them.
Yep, I'm sure USD hyperinflation is right around the corner. Eminent economists such as Peter Schiff and Ron Paul have been predicting it for decades. They can't always be wrong about it, can they?
The fact that the yen has fallen against the dollar means that yen are worth less in countries where they use dollars, but not necessarily in places where they use yen. If yen were worth less in Japan that would reflect itself through higher yen denominated prices on stuff in Japan -- it would show up in inflation -- but inflation in Japan is somewhere south of 2%.
