Based on my study, it would be better to have ETC, XMR, NXT, VSL, ICN and SNGLS in your portfolio for now. You can flip them after 4 to 6 months or hold on to 2 years time frame and see for yourself. The future is for the next killer Dapp and I think  VSL, ICN and SNGLS has potential. ETC, XMR and NXT has some more room to appreciate in value.
