Stone or Jade

Stone or Jade — 一刀窮，一刀富 One cut dust, one cut destiny.

Cut open blind stones to find jade. Trade it on a pure player-to-player market — there is no pricing formula anywhere in the code, and money is conserved to the cent. Above the market, a rule-based central bank reads the public trade tape, adjusts the weekly UBI, and publishes FOMC-style statements you can audit line by line.

You join a server whose economy has already been running for six weeks: the price chart, trade history and six central-bank statements are on screen from your first minute. Open the Economy Observatory to watch a full 26-week policy cycle in two minutes.
