Pledge 10 xmr to the phoenix initiative.
I would prefer a different approach to raising the funds (small tax on M, sell proceeds OTC, everyone pays for the work), but if the fundraising goal is met through pledges all well and good. Most decentralized projects suffer from free rider problems, and looks like many CK players are not actively following, so some who might pledge may not know of Speed's proposal. Still, crypto types are libertarians, so enforced taxation even for a 'good cause' can create bad vibes.
I suggest creating a fundraising asset on Agora to match donations, it would cost nothing to do, and would record who gave what. Benefits might accrue to holders of this asset at a later date (discounts, airdrops etc), and even without making any concrete promises, the possibility of future benefits plus the recognition would encourage more people to pledge.
The tax would be: 150 (xmr needed) * 100 (m3 units per xmr) * 5,500,000 (m3 midprice) = 82,500,000,000
Spread over all the players, this would bankrupt quite a few.
I view this as a start for speed's plan and agree with him that players will fund this without the need of further prodding (though 25 Billion should incentivize too). Long term I believe he is working on a self-funding model--though I'm unsure as to whether that happens in the next iteration or further down the line.
If you are volunteering to put a reward system together and manage it--great. I was planning some honors for this initiative, but would gladly hand it off to someone else--especially if they have a permanent reward system in mind.
