Is it a good idea in your opinion for me to wait for ethereum price to increase so I can sell it and move the money to more alt coins or should I just move the current amount of ethereum to other altcoins right now? 
You should buy things with a reason. And then if over time that reason still exist you keep that thing. If that thing lose that reason then you sell it. If you just buy without any reason then you have a big problem. Since once you have it you have no ideas if is valuable to you not. Buying things that you dont at least believe are valuable is a bit silly. That is like I would buy a car without an engine.
