I can provide my experience with first purchase of MAID. It was like 5 months ago so It should be still actual.
I got some altcoins but I wanted to start my journey at beginning, so I purchased bitcoin via locabitcoins, then moved those coins on poloniex and exchange it for MAID.
As we all know exchange is unstable so I moved my MAID to omniwallet.org IT is really easy and straight-forward. However this is still online wallet so there is always a risk. In this concrete case I wanted those coins as a long-term investment so I find this discussion and for the detail advice with your new paper (cold) wallet you can see three post behind the previous one
Hope it helps to someone
