NIX is moving to POS with around 6% staking return!!!!!!!!! Wow great news. https://nixplatform.io/announcements/nix-pos/
Right now about 46k are mined and hit the market each day. Once POS is activated in the next few weeks that will drop by over 50% to 20-21k per day. This means  it will be much harder to acquire a ghost node, and likely higher prices. Fill your bags now, or ghost nodes will likely become very expensive...
