Xtrabytes is my top pick for 2018.
My newest investment is a low market cap community coin that trades on Cryptopia called "Zero" ticker symbol ZER. With a 4ish million dollar market cap throwing $20-30K in seems like a no brainer. Going to use my clout to try to get it listed on a couple of other exchanges and help the community any way I can. Easy $20M market cap coin, if not $50M plus... (a 10 bagger from current prices)
I also have Pascalcoin. It's limitation is only being listed on poloniex. As far as tech goes this tech is proven it's just not very well known or utilized.
https://www.youtube.com/watch?v=F25UU-0W9DkArk is another favorite of mine.
I continue to keep my eyes open for new opportunities so I read threads like this. I figure I can add my picks. I like to focus on tech first but if it looks like it's simply gonna make me some money, I will buy it. Don't care what anyone thinks. See my sig.
Other coins I might be inclined to pick up.. COSS and Elixir.
