Bitcoin and Ethereum Divergence

Since the beginning of the year the Ethereum and Bitcoin divergence has been enormous. Honestly I am not sure why. I do understand the applications for Ethereum for out ways the potential for Bitcoin but I also understand Bitcoin potentially replacing Gold and potentially many sovereign currencies especially in emerging markets. Both seem to have enormous potential and both have been on meteoric rises so why the divergence since January? Technically speaking both are still bullish trend but Bitcoins weakness is a little bit more troubling in the near term. Please comment with ideas
