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? 
maybe if the new altcoin you are talking about really rising now or has a huge potential to rise in few days from now, then you should sell your ETH to that coin rightnow, but if not then you should wait until ETH price high enough to sell for another the altcoin.
