What everyone is missing is the Ethereum long positions. These started going up 7/15/18 and are almost at record levels. Longs have been accumulating Ethereum ahead of the CBOE futures launch in December. Shorts have been closing BTC short positions out due to ETH eminent rise as December approaches. But unlike ETH, BTC longs are not going up. This is because the EOY trade is ETH...nothing else. Now that being said BTC will go up also, but smart money wants ETH. Smart money always ahead of the general public. Look at the footprints they leave and then trade alongside them.
Keep in mind BTC went from 5K to 20K on the futures launch trading into new highs. Ethereum on the other hand is 1000 points down from the highs, which implies it has quite a bit of room to run before reaching ATH. Really don't care what BTC might do during this time. As ETH rips it will become more and more apparent that the trade is to be long ETH, only ETH.
