the lowest marketcap. in my portfolio has TKS (Tokes) with 1 mil.
there´s an active team behind it and the progress they make is also nice so far.

Also SHIFT has low cap (8Mil.) & APX (3Mil.)

I´d recommend you research the details of them on your own, so you do not have to depend on my biased opinion. (I am holding these 3 coins)
