First of all, thanks for all your replies.
@Barbarian , the thought of reorganizing my portfolio happened before I have loses (my english is so bad I don't know how to even express myself properly), Hype + FOMO were mainly the causes of that portfolio(hi there TRX, KIN, XRP, TNB, ...), that's why after some days I think I should reorganize it a little bit.
In my case, as @Poink I would like to hold some coins no matter what (like I said, ETH, XRB, then IOTA, POE and maybe ICX) for long term while some others are just to play a little bit. I would like a portfolio with a 70-80% of coins just to hold and the rest to look for new opportunities...until I get tired of it and just have a 100% hold.
I'll continue reading all your advices, thanks again.
