DXY vs BTC/USD

Correlation does not imply causation. However, the dollar is causal related to both observables: BTC/USD & DXY by definition. It is unlikey that those observables are not related when the dollar causes the money flow between these 2 spaces in which they operate by definition. BTC/USD & DXY can be causal related whilst exceptions may occur.
Challenges:

• Which model predicts the causation with the highest probability in a dynamic way?
  
• How is the strength of the dollar observed as the causation of derivatives ?
  
• What attributes to flux between the operational spaces of the dollar?
  

Bitcoin seems to react on demand pressure of the dollar through the years. As the wind causes the windmill to be active, the dollar encloses temporal incentives to let Bitcoin find its way until the end.

DXY: The U.S. Dollar Index 0.18% tracks the strength of the dollar against a basket of major currencies.
