Popular perception is that the renminbi is undervalued, i.e. the Chinese keeps the rate low for their own benefit. Why did it fall when it tested, ceding to market forces?

I'm 26, have $450k liquid, and $200k salary. What should I invest in that is high risk/high reward, but creative/interesting/atypical?

Please tell me if those questions are the same.
