Because this is not close to passing and is no longer receiving additional support, it is reasonable to unpin it, especially since there are so many other pinned topics.
I still think this motion is a good idea. In light of the powerful affect our first share buyback in the amount of $2500 had on share price, we can understand the importance of holding down costs.
It has been criticised because it would make the peg somewhat asymmetrical. There are other factors already at play that make the peg asymmetrical. A preference to avoid the volatility and additional risk of BTC appears to be causing the sell side (where NuBits are used) to be favoured at the current time. Therefore, a counter measure would increase liquidity wall symmetry. While fixed cost liquidity is an exciting innovation that is likely to reduce liquidity costs soon, we have every reason to pursue as many cost cutting measures as practical.
