If Manifold ceases to allow mana withdrawals, will mana experience significant inflation within the next year?

If Manifold turns off the ability to turn mana into charitable donations or other items of significant value as described here, will the quantities of mana in use on Manifold experience a significant increase, along with a decrease in how much traders intrinsically value 1 mana?

This is common problem in play economies that give out bonuses to reward behavior they want to encourage, but don't have a good way to remove currency from the ecosystem. See the former MTG trading site Pucatrade for a nice case study on how abundant free money giveaways led to runaway inflation and the collapse of the site economy and eventual shutdown of the site.

  • If Manifold turns off the ability to cash out mana and significant inflation occurs, this market immediately resolves YES, no matter what happens after that.

  • If Manifold turns off the ability to cash out mana and no inflation occurs for a year, this market resolves NO.

  • If Manifold turns off the ability to cash out mana and then turns it back on after less than a year and no inflation occurred in the mean time, this market remains open without resolving until the next time they turn it off. (If it looks like the reason they turned it back on was due to signs of inflation about to occur, that will be sufficient to resolve this to YES.)

Mana is being devalued 10x and will no longer be donatable to charity; should resolve yes

Recommendation: "Inflation is defined as the average percentage difference of mana balance in [10, 25, 50, 75, 90]th percentile users, as measured at the beginning of the year and end of the year".

If some of those percentiles are different("massive inflation for whales, massive deflation for everyone else that keeps losing money"), then the ground-truth calculation is to resolve PROB to a percentage calculated over all percentiles rather than just 5.

Significant can be whatever you want, but using that metric.

Hmm. Any thoughts from other users?

How are you defining/measuring inflation? Because if mana suddenly has less value because you can't redeem it, is that inflation? Or if mana suddenly gets mass-donated to charity, that would be deflationary, right?

@MichaelWheatley Inflation meaning that mana seems worth less subjectively due to existing in greater quantities.

For example, if Manifold ever changes the cost to buy mana to make it cheaper than 1 cent per mana, that would probably mean this market should have already resolved YES.
