How it works

After this market closes, I will ask @FairlyRandom to generate a random number M among 1 to 200 in the comments. The Mth unique trader of this market wins 500 mana from the lottery prize pool, if such a trader exists. Otherwise, the lottery falls through till next time.

For free play, make a trade with 1 mana and sell it. Your trade will be recorded and you will become a unique trader.

This market will resolve to x%. 10^-x seconds is the order of magnitude for how long fast radio bursts typically last.
