Majority of the coins are depending to bitcoin so if bitcoin goes up, they will go up too and vice versa.

If you ask to a nocoiner, he will suggest you to buy more those altcoins but good thing you ask to the people here who are holding the real piece, bitcoin.

Why you are not adding bitcoin to your portfolio? While it's early to get bitcoin, get some of it so that you'll definitely get enough profit once it rises again.
