You're absolutely right, the volume is what matters the most.
Here's some assumptions and goals I based the calculations on:
- An initial milestone is to capture 10% of the overall network traffic (10% of posts originating from chainBB, currently hovering around 1%)
- 15% of those rewards split off to chainBB (with a portion of that going to community owners, let's say 5% for this example).
- Pre-HF19 the rewards pool was ~50k/day (which is when this math was done).
So if we say 10% of daily rewards (50k * 10% = ~5k/day/value
) is what the users are generating via chainBB, and 10% of that value goes to chainBB via beneficiaries, that's around 5k * 10% = ~500/day/value
that chainBB can generate. 500/day is roughly 182k/year in earnings, which is enough for:
- 1 (maybe 2) full time developers
- 2-3 small contract developers/designers
- Hosting Costs
Looking at 5% in this equation, you can basically cut it all in half. So 5% rewards @ 10% of network traffic would be ~90k/year, which would include a pretty low developer salary after hosting costs and some contract work are removed.
All of this thought was pre-hf19 (when distribution was stable) and assuming STEEM is approximately $1.5. Currently after HF19 the rewards pool is unstable and I'm waiting for it to become stable before I rework the math - it's fluctuating pretty wildly right now.
Your calculations are reasonable. But you should take some factors into consideration:
1 - Steem is expanding daily and the number of users and posts is booming and expected to continue like that.
2 - After hf19, the rewards has increased dramatically.
Best of luck.
Both are true currently, but not guarantee's for the future.
Thanks for engaging me on these topics - they're important discussions and I really appreciate the thought you're putting forth towards this!
