60-70% above are weekly/monthly resistances on ETH/BTC pair.
Longer the base higher in the space: ETH has developed a solid base before entering this uptrend against BTC. So there is a small chance that ETH can reach new ATH against BTC. But that would mean 'The fippening'. I am not counting on it untill it happens.
BTC is THE King, untill it is not. ETH is NOT the King, untill it is.
