I would put 500$ on NEO and the rest on electra (ECA), car vertical (cV) and revain (R)
NEO, CV are the two that i have put my money recently.
Revain is good similar to CV but Revain is for rating and CV is for cars information stuffs.
I like revain and will probably invest some of my this months salary into it.
The new ICO
farmatrust is also cool, have a look at their white paper.
