Thanks @cyrano.witness, I appreciate the write up - I was going to do a write up on this topic but have been swamped with Gridcoin things recently.
I'm very interested in seeing the current 'black swan' state resolved for the Gridcoin MPA, however this will likely continue occuring due to the volatility of Gridcoin's marketcap.
On a positive note - this is a great learning opportunity for all BTS users, it's not often that black swan events occur, better for it to happen on a new MPA than one of the large ones (fiat/btc).
I'm not going to give up on BTS, i've been holding BTS since BTSX so i'm very much so interested in seeing it succeed.
I've promoted your post, let's hope some Bitshares users join in the conversation! :)
The Gridcoin MPA does not have the permission "override_authority: Issuer may transfer asset back to himself" as it was surrendered in the pursuit of decentralization. https://steemit.com/bitshares/@cm-steem/should-the-bitshares-committee-surrender-overreaching-mpa-permissions
There are currently only 4 holders of the GRIDCOIN MPA, I attempted to 'settle' my balance but without a price feed it doesn't work - we could potentially approach the 3 other users with the correct instructions to resolve the current black swan state, but if in the future we had 100+ holders this would be far more difficult.
