Yes, it is not at all clear how they can think this, Ethereum is the most realistic project of all with a great future. And the price can start to grow, even if Bitcoin will not grow. Just a chart can go up bitcoin and dollar.
from last year, we need more time to recover but with stable increase, I think I would accept this and will still remain bullish.
BTC has price when ETH rise, this explains that BTC is so dominant, I have observed in the past that when BTC rise ETH will fall, so I
really think I like when Altcoin will dictate the market movement so we will all see what we are expecting to see.
