You are giving me the chart of the market's trades, not the asset's value. Some people are stupid enough to trade without understanding what they are doing with regard to the exchange rate (see this thread), so try looking at the end result instead of the market perception and maybe you'll grasp the concept? When you break everything down per trade in USD value, you can actually see the real performance of these assets, most of which are still horrible.
Maybe I'm one of the stupid ones, but isn't an asset's value determined by what people would pay for it on the open market (among other things)?
What if you want to hedge against dollars and Bitcoin?
Buy gold and silver? How would buying a BTC-denominated security hedge against BTC?
