What are you talking about? Most altcoins are in green as well. This is something really different unlike 2017. With many crypto adoption and news about big companies this is really something good for the whole market. Of course, btc will dominate the market.
of course altccoin rises and greens in fiat when bitcoin rises, but in the corner of the pair with btc, altcoins are much down like ethereum. but that doesn't matter to me.
