Avoid Armada markets and indeed any other unregulated broker like the plague. Ignore any claims of segregated accounts, because when the sh1t hits the fan, you'll have no recourse unless there is some regulatory body to protect you.
I think regulation is overrated. If, for example, Armada Markets and IC Markets go down I wouldn't expect to get a single cent of my deposit back from any of them, whether IC Markets is ASIC regulated or not. This might be different in case the client lives in the same country as the regulation authority, though.

Also, there are situation when I prefer an honest unregulated broker (meaning they clearly state the fact that they are not regulated on their website) over one that actively decided to set up shop in Malta, Cyprus or Mauritius, just to name a few.
