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.
I do not agree. practically all altcoins are lost and continue to lose to btc. all altcoins are red. if a dollar is taken, some coins have grown. Especially against the dollar, strong growth has been shown by eth, etc, ltc.I hope that all altcoins will soon begin to grow ro btc
