Ethereum rises, and the altcoins continue to rise.
Bitcoin rises, and the altcoins keep falling.
What does it mean?
It means that the rise of BTC has nothing to do with the funds in the circle, and it is all driven by institutions. The funds of institutions will not overflow to the altcoins.
The rise of ETH is the real drive of funds in the circle, which can bring about the explosion of the altcoins!
