Please, i have no interest in your projections, I'm more interested in the technology behind the coin you deem your favorite for 2018. So having said that, what is YOUR favorite coin, and what will it do for: technology/blockchain/financial fields?
There is privacy coin from Russia called sibcoin. Take a look maybe it will interest you. Can be mined, uses masternodes if you are about that jam, community is growing also low fees.
