I like being able to go back and forth between a wide variety of assets as they cycle against each other in the market.
I can switch between BTS, BTC, Gold, Silver, CNY, EUR, and USD for about a penny in ten seconds as often as I like.
I can also create my own basket of currencies and adjust the mix as often as I like for pennies.
And I never encounter the delays, costs and risks of passing through fiat space.
Where else can you do that?
