Checking out ETHBTC pair for general market condition

They say that ETHBTC pair can tell you when the bottom is set for general crypto market.
We shall see that in April. I have converted all of my altcoins that I accumulated lower into BTC and ETH in the past week. LUNA/BTC pair gave me the most profit.
I am not using this to buy or sell ETH spot bag. I will probably use this to SHORT/LONG ETH at defined levels.
