I think Intensecoin is a pretty safe bet at these prices. They are trying to develop a distributed VPN as well as making a decentralized platform/marketplace for decentralized network services. Its speculative because the product isn't ready, but if they pull it off it could be a 20-25x. Compare the number of tokens they plan to have versus sia, and it could be epic.

I like Spectrecoin as a top pick for privacy\anon. They seems to have great devs and are open about their development. Once transactions use ring signatures by default and the unique stealth staking are rolled out, it will deserve to be up there with Zcash and Monero. Very few privacy coins are actually developing unique features. I think the fact it is PoS is going to help it long term. If it hit the same marketcap as verge did,  it would be about 105-110$, I like that kind potential.

Zencash is probably not considered low marketcap, but as a competitor to Zcash, it seems like a very well run project with quick development. With the securenodes and their other projects, it seems like a good one to hold long term.
