This proposal isn't meant to address downward failure of peg, but that hasn't been much of problem, since HBD holders tend to increase conversions to Hive as haircut is approached.
But if the concern is that this mechanism would get us to the haircut ratio too quickly, another option I've thought of is to stop allowing conversions at some point before the haircut ratio even. I'm just not sure that it's necessary. I don't think it would be advantageous for a Hive->HBD converter to approach the haircut limit, because it increases the chance that the HBD they are creating for themself would lose value due to the haircut taking effect.
If it gets to the haircut ratio too quickly on a regular basis I think that just tells us we should increase the haircut ratio (within reason). This means there is more demand for HBD, which can be transmitted into demand for HIVE, and we shouldn't be arbitrarily capping that at 10%. This is the value of yield farmers in capitalizing a token. If it turns out that the demand mix is such that people want to invest in Hive more for yield than for speculative appreciation, we should let them.
Yes, I agree.
stop conversion before haircut ratio is reached,
stop conversion if result of 3 day average results in a loss for the trader (protecting noobs). Maybe start activation at 1.07$ for the last 3 days average.
Yeah, it's not very likely but I had worries about it mainly because of seeing under $1 SBD for too long. Thanks for the explanation.
