Bitcoin as we all know is the number 1 cryptocurrency by age and market cap, so it's upward or downward movement can affect other cryptocurrency projects.
I believe so.Since bitcoin dominates all other cryptos,it is not new to us that altcoins are bound to move similar with bitcoins.So if bitcoin starts to move in an increasing,upward trend,then expect that after few days you will observe that altcoins too are increasing their prices too.It just proves how bitcoin has a very strong foundation despite all odds.
