Those two coins are quite good with prospective of long term investment specially NEO. NEO operates on smart contracts and has high scalability and aims at connecting the outside world to the blockchain technology to solve various real life problems.

NEO also provides passive income to its holders in the form of GAS. Deeponion on the other side is a privacy coin and I said to be one of the most anonymous and decentralized coin in the whole market. It is still quite undervalued and has huge scope of growing according to me.
