I have recently took investing on poloniex serious. Ever since I've invested the alt coins have been down. Do the amount of coins I posses go up if I stay. Also, do I have to wait for the coins to go back to their original price that I bought fo in order to make a profit? What are the reasons to holding if prices are down? Thank-you.
Personally I always like to HODL eth. With alts I pick a price I would be happy selling at and if it reaches it I sell.
There are a lot of coins in my investment portfolio. And some of them have become cheaper, and some have grown significantly. I advise not to worry, because, all the Crypto currency is growing, even despite fluctuations
Its good that you have diversified your portfolio so that all eggs are not in one basket. A particular coin may flatter but investing in many coins will yield you good results provided you have invested in right coin. Also keep in mind that mostly value to altcoins depends upon btc, if btc moves up they also tend to move and other way around.
