Same thing that everyone is asking everywhere ,the fact is some experts believe that altcoins won't surge in price like the past bullrun ever again but I did noticed something in the past, altcoins don't surge right after bitcoin start surging ,not immediately ,it takes time even month before altcoins start appreciating on value ,remember last DEC 2017 bullrun? Altcoins favours mostly on Jan 2018
With altcoins the name of the game is patience and time. Unlike the bitcoin, the market is not right now into many relatively unknown alts unless the people behind the platform are doing their homework in growing their community and making sure that people know of the many new developments happening. Information dissemination is very important for many alts so if I were a part of the devteam I will always update my supporters and practically everyone the things we are doing. This is just a matter of herd mentality...when people sense that more are getting into a coin the more it can attract more buyers and believers.
