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? 
Ethereum is giving some signs that it is ready to make a move so anyone thinking about selling their coins should reconsider it, I know that ethereum has not performed really well lately but it seems to me this is going to change and if that is the case you do not want to miss the movement after you have waited for so long, then after you get your profits you can sell your coins and do whatever you want with them.This is, if we are contended of the profit we can get today then better to sell it now but if not, nothing to do but to wait another pumps again.
As I look the market situation, it really positive that ETH price will rise as BTC keep on moving and we might be able to see bull run again. May hoping that you can wait for that and to have more profit than of selling it today.
