It seems you are aiming for a very fair way to distribute almost all of the coins. This can rarely be observed in crypto. What kind of services are eligible for bounties?
right now the best ways to earn are voting on tradesatoshi and being active on our forums. There is more we can do with the system we have in place, but the more complicated it gets the harder time people have understanding it. The website will likely become a secondary means of earning and we will switch to a more traditional bitcointalk signature airdrop system. The website gives us a lot of functionality, but most users would rather just get the airdrop within this forum system, not ours.
