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...
Not only that, miners ussually mine and sell due to mining costs and because that is the business. With POS all current mining rewards will go either to GN or NIX holders who aren't so willing to sell.
