How long do you intend to hold these coins for? And may I ask, how much are you investing per coin? There are lot of coins that you have your toes in 
How long depends on the coin performance. The list changes constantly.
These are just the "cheap" coins
...I have around $20,000 on these.Like many, I speculate.
Between VEN, REQ and EMC2 I made all my money back (and more). Got lucky selling them at their high.
I consolidated and from the posted list, I only hold VEN, REQ and RPX now. The rest were all sold/reinvested.
