Way to Survey-Way to make money at home, paid surveys

I feel like I'm losing money everyday keeping my savings in USD. I live abroad but kept my money in USD because I just kinda figured it was safer, but boy I should've switched it to RMB (Chinese yuan) a long time ago.

Now I'm moving to Japan in a few days and wonder if it would be better to take out all that money now (in China) and then switch it from RMB to yen, or if I should wait til I get to Japan and just switch USD-YEN. What's the best plan of action?

I heard the dollar just fell a whole bunch against the yen, so thats why im asking. I don't really understand the currencies market…

I have done a bit of research, one or two of the tutorials and a trial demo on one of the websites. I was just looking for some feedback from anyone that is trading or has traded it before.
