At 115,200 HIRO produced daily we will require 0.1152 BTC to buy ALL HIRO produced that day. I don't think that is anywhere near too much and will not quickly destroy the value of the coin. At 5 HIRO a day you're suggesting that we'd produce 7,200 HIRO daily which would require 0.0072 BTC daily to buy. That's a bit extreme and definitely skews the distribution to anyone who holds/buys HIRO now.
We're at a point where extreme ideas should be considered especially if they address a known issue. To tempestb's point, investors like us (those who hold a whole lot of hirocoins) need a reason to hang onto our coins. In the absence of one, we're talking about millions of these coins being flooded into the market, in addition to the 115,200 HIRO produced per day from mining...what would that end up doing to the coin's value?
I've seen tempestb's buy walls across the exchanges, and it's pretty clear without these, the price of hiro would easily be in the 60-70 sat by now; possibly even lower as there have been days when buy pressure was severely lacking (his walls have actually brought on additional buyers).
How about a reward model that is broken up into phases with milestones attached to each? The first phase introduces a substantial scarcity of hirocoin. During this time, we give the coin a chance to recover, and if it hits a target we set as a community, that's a trigger to go into Phase 2 where the production of hirocoins is allowed to increase. Then phase 3 and so on. The rewards can remain dynamic per phase, but the swings are tighter and far lower at the start.
Below 115,200 HIRO would be extreme in my opinion, but I can bring it up to the rest of the team and get their thoughts. If we fail to create a mere $60 in buy orders to buy ALL HIRO produced daily I think we've failed. Even without the buy walls at 100 satoshi, we've had at least 0.5BTC in volume daily which is incredibly low, but enough to absorb 80 HIRO block rewards.
The reward model as of now is similar except it will be in place hopefully for the foreseeable future in order to provide price stabilization. But I get your point that you'd like to see a more scarce reward in order for the market to recover. I'll let Hiro know about these suggestions and see what he thinks.
