I would encourage you to investigate on BTS. It would expose your portfolio to DEX, which is, due to classic exchanges being hacked, and the fact that you do not own the private keys on such exchanges, going to see rise in popularity.

Also, when you have no problem having both ETH and NEO, why not throw in some EOS?
And finally, there are rumours of XVG starting to fall apart.
God bless!
