If I am the one who'll buy, I prefer to buy NEO / EOS / ETH since they are strong coins. Those coins will really strengthen your position and lessen the risk of losing your ROI. Though the alts you are watching does appeal to me personally and they might have great potential in this market, there's nothing wrong about being too careful, right? But if you want to gamble on those alts, feel free to do so. Higher risk gives higher gains
