Rate My Crypto Portfolio

Hi,

Here are the various currencies I am holding onto:
Bitcoin
Litecoin
EOS
IOTA

I am planning to buy the following coins:
NEO +Gas
Ark
ADA

So what do you guys think?
Should I buy more of the coins I already own?
Out of the coins I intend to buy, which one do you think I should consider the most?
If there are any other coins that you feel I should then do let me know?

Thanks in advance
