BTC went up - alts went down, BTC went down - alts went down, this was the case before December, when cryptocurreny market pumped last time.
But according to coinmarketcap BTC dominance in crypto market is 34%, though it was more than 60-70% on September, doesn't it mean that people started paying more attention ta altcoins and so alts eventually becoming more "independent"?
I don't think it will happen this year or even next, but don't you think that some top altcoins may bypass bitcoin in the near future?
You are comparing one of the lowest points in market dominance against one of the highest point in the previous year, so the difference is huge, also as time passes the dominance is going to get lower as more projects that are worth our investments begin to appear, so this is nothing to be surprised about, however the day a coin could surpass bitcoin in market cap is still very far away.
