I know, it's maddening.  And I've been there (a lot!), you figure, hey this guy says it will most likely go down in price before it rises so I should sell then buy back when it drops and I'll have **EVEN MORE** when it rises.  I have done this, and it didn't drop much, then it rocketed up without me.  So not only did I sell at too low a price, now I didn't even have any more to sell at the higher price, and if I buy back in I'll have less...and it may not even go up anymore!!!!!
If you really want to try to day trade to catch the wave try it with a **SMALL PERCENTAGE** of your position.  Say 10-20%.  See how you do, and that way if it backfires you still have 80% of your position in the bag.
There are sooooooooo many predictions, you will go nuts trying to follow all of them.  I would say just try to get a sense of the *long term* for the coins you have, that way if it drops and you get nervous you know that it will rise again.
Hope this helps man.
