There's nothing wrong with the altcoins though it's just that most of them doesn't follow what is the trend of Bitcoin that's why most of them got left behind.
There's nothing wrong indeed, depends from how the creators will make progress that's the thing that will bring them into this trends.
Yeah maybe some people think that altcoins grow out of no where, the team behind the development is the core of the success of the coin so if an altcoin price is surging that is because of the speculation of the people because of the progress that they are making, in short people are trusting them.
Whereas ETH for example is totally on a different side of the rest of altcoins, it breaks a new price resistance which is most speculators been waiting for too long to happen and here it is now.
Good catch for every investors who entrust their investment to this project, after that huge dip it's now breaking its way to the top,
expectations coming from those spectators will create more rise to this project.
As for eth is concern this coin already has its name mainly for being the 2nd in the market after bitcoin so doubting it would make us fool to believe that it will not be running with bitcoin. No matter how low it gets, it will rise just like bitcoin. This year, I see ethereum being bigger than the bitcoin in terms of price increase percentage, bitcoin could just be 2x of its price right now, ethereum could get 5x.
