Your comments were very valuable to me and helped me a lot.

Now, after doing some studies according to your suggestions and my initial study for some coins. I decided to increase my investments to 3 btc that's all I have.
I will keep 1 btc and divide the other 2 btc to 4 parts each part equal 0.5 btc for investing each in one coin.

So my portfolio will be
a) 1 btc will remain as it is
b) 0.5 btc will go for ETH
c) 0.5 btc will go for LTC
d) 0.5 btc (not decided yet)
e) 0.5 btc (not decided yet)

For d & e, I'm still thinking between
ZEC
DASH
DECRED
EOS
ONT
BNB

What are your opinions guys for that? And is it better to buy now or I should wait until btc stop rallying?

Note: I also have two alt coin called CHZ & CXO that I' holding from long time because I believe in their projects.
