Dev is currently working on migration . Should be back up on Bittrex soon ! .
Some of the early coin-holders talk of a wallet that they have or currently use. I do not know of one myself . 
I also have seen that the developers working on a new wallet.

All will come in time from what I have read on #Slack .
The holidays were upon us and I believe all were taking some much needed family time and now the developers are working at it !
To The Moon , this is going to be Yuge  !
