Actually, the three coins: Bitcoin, Ethereum (or Ethers) and BitcoinCash are all surging ahead...as if they are conniving with each other ...
This could also be explained by the fact that all of the coins that you mention have USDT trading pairs. If you take
a look at the huge increase of the outstanding Tether supply in November, you will find out that this new money
(backed or not backed?) is actually driving the surge of all these coins.
Margin markets at Bitfinex are at all-time highs and have increased a staggering 50M $ in the last 24 hours.
This could get even crazier if they release even more Tethers in December.
