Try ABY
It had great growth in 2017. (for 1$ investement on 1.1.2017. you could get over $200 during the year -- info from their official forum).
Technically, implemented segwit2 etc.
Idea behind it is little "limited", primarly an artists coin... but has strong community, little over 10mio USD market cap...
You can get it bellow 150 sat... Mining is not profitable, but buying may be.
