I was expecting OP to give reasons why he thinks the coins on this list have potentials but that's not the case. Anyone holding BTC right now shouldn't invest more than 30% in altcoins in my opinion, Bitcoin is the real deal right now if you understand the impact halving can cause. I'm yet to analyze the coins listed, but I think you are missing out ETH of course,  XRP and XLM. I also think NPXS will do well in future. The development progress for these coins have been massive and we all know ETH will be switching to POS algorithm.
