The Fibs seem to match the ETH/BTC movements of the daily candles pretty accurately and although I'm not trying to guess how exactly the price action will behave, it looks like ETH can move from where it is (Close to Fib 0) to the local high (Fib 1 - 0.041ETH/BTC from dec18 to jan19).
The blue line on the bottom is at 0.023ETH/BTC and seems to be the lowest point...
