Just come back for a few months to see what DeepOnion did, the team is still active but I don't know why the price is too low now. Is it a reason for this?
Different reasons, the main one is that the general crypto market has been down since Feb-March of this year and many altcoins were and still suffering that bearish season, it seems that things are starting changing slowly; time will tell.
But DO is getting better with new codebase including so many great features like Lightning network, segwit, smart contracts, DeepSend!, etc! and it has a MVP available for everyone to use worldwide!
