According to john mcafee privacy coins are going to be big this year so you should add some of those into the mix. Also, i'm surprised you missed out NEO which is pumping quite well recently, even when other alts are falling
I don't really like NEOs but I'm impressed with its performance too, might be a good investment for 2018, especially if China's politics might promote its growth as well.
It sens to me That NEO is a bit more stable in growth than many other coins. But also its a bit pricey for beginners in cryptoland (my opinion)
