I highly recommend on this following 5 altcoins to invest:
1. Minereum
2. DeepOnion
3. NEO
4. Ethereum
5. Signatum
you have to make a research on these altcoins.
Absolutely agree with the recommendations above.
it may also be worth a small investment in BitBean

My best lists are ethereum, neo, deeponion, xmr, mgo and waves. These are my best altcoins these days that until now I hold. Deeponion is the best also and I believe I can earn profit.
