Anyone think about this? I've thought about it a bit, as I keep track of currencies because I used to buy a lot more stuff online from Hong Kong and Japan. Like today I looked at the yen and it's about equal with the USD(908 yen per 9USD). But at times, you used to be able to get only 85 yen per 1USD, but at other times the exchange rate is the opposite, and it's like 115 yen per dollar. The pound used to be worth a lot more, too. And Canadian dollars when I was a kid, you could get 1.5CAD per 1USD. Now it's equal.
I'm wondering about forex trading and exchange in general. Is it really risky? Obviously if you had a bunch of, say, old Iraqi dinars from the Saddam era, they're barely worth the paper they're printed on nowadays. But with relatively stable currencies? If I had some Canadian dollars in like 2001 and held on to them by 2008 or so, I'd have gained quite a bit of money from it going up to equal with the USD.
I don't have a lot of cash, though, but is it wise to buy some foreign currency even in amounts of, say, 100USD and just hold on to it and use it when the time is right? I'm not so sure about reselling it, but using it to buy items/services in the country of origin could be a neat idea. Anyone have ideas for other currencies to look into besides the yen? The yen interests me most as I've seen it go up and down over the years, and I could basically hold on to some yen and in bad times use the yen as, say, a 20% discount card getting stuff from Japan.
Thoughts?
