Well, as for the SBD peg to $1 US, it needs to be stated that the markets have done their thing.

The most that the TOP 20 witnesses can do is to put downward pressure on SBD.
One of the tools available for this is BIAS. However this isn't an outright solution, but it can add a little downward pressure on the SBD price to get it to $1.

Any action that can at this moment put downward pressure on SBD should be considered and if feasible put into practice.

As for the "bidbots" this is an opinion that I have seen out there, but remember, it is a free and open market. Personally I believe that they have contributed to the internal debt situation. They are definitely not the exclusive cause of it.

Believe it or not, they too can be used to put downward pressure on SBD, if they were to be temporarily limited to Steem payments only (for their services) than this would result in many more people selling their SBD on the market and not just a handful of bidbot owners. Hence again, putting downward pressure on SBD, getting it closer to $1.

Once it gets to a $1, reverse conversion of Steem to SBD seems to be a viable long term solution. Again, time will tell, as with everything out there, I don't doubt that some shall try to manipulate the markets if it is possible.

So in all fairness to the TOP20 Witnesses and the topic of pegging SBD to $1, they are not "God" in the system, yet they have not utilized the BIAS option either. So it is a rather painful issue when one looks at it, as HF20 comes closer, so to do the SMTs and potential billions of $. So priorities are at question more than anything else. Not picking on anyone in particular and I am certain that among the TOP20 many are concerned about these issues more so than what may seem to be the case. Again, very tough topic to get into.

But the more people like yourself who bring it up, the better it is for everyone. Sooner or later, something needs to be done about it!
