Note on rule changes to the We changed the rules so that you’re only allowed to donate to a cause at the end of your turn, this is to prevent token sniping. this is justified because:
in a real market valuations will change dynamically due to arbitrage and automated tools the real value of index currencies is that they act as a “commitment device for carrot” which empower value aligned vendors
To add in the future:
coordinate into groups in order to fund the causes they care about (e.g. multiple causes) give each player a unique bonus score for donations to causes, e.g. Alice gets $1 per $10 donated to Rescue Animals, but Bob gets $2. Permit assigning negative scores as well.
