The problem with option 2 that you present is that there was a severe price imbalance the last few days where purchasing selling and mining individually would add up to be a fair degree less than the cost of a PURCHASE, making it hard to accurately determine ratios. Furthermore, I think that actually attempting to determine anything based on "what seems to be fair/correct" will devolve into a shouting contest between the two sides in which the outcome will more or less be purely subjective.
Anyway, I would prefer to not move to another exchange but rather follow through with the buyback clause that was in the contract.
If MINING + SELLING was X% less than the NAV/U of PURCHASE (which, remember, is 5% LESS than the selling price of PURCHASE) then it's rather simple to convert them to add up to NAV/U whilst being in the same ratio to one another.
I'm not sure which buyback clause in the contract you refer to:
If you refer to repurchasing PURCHASE and matching bundles of MINING+SELLING then yes - that will of course be possible once we've established what NAV/U is. The only real issue I see with determining NAV/U will be the Ciphermine bonds. Those won't be refunded by the issuer as the cash from them has been used to purchase mining hardware. If the bonds relists elsewhere then there's no problem - otherwise, per the contract, we have to give notice of redemption and wait three months with zero interest before the cash arrives. And until it does I can't in good conscience include it in the NAV/U.
The contract, on closure for exceptional reasons (which this is) says :
"Propose a split of funds between DMS.MINING and DMS.SELLING to be approved by a majority vote by both all outstanding DMS.MINING and all outstanding DMS.SELLING.
In the event of a vote with a proposal to split funds being left up for 7 days and (in either vote) the total of (Yes votes + No votes) being less than 50% of all outstanding shares then the Manager will determine a fair (in his best judgement) split of funds and execute final payments in accordance with that decision. This clause is added specifically to address the scenario where most shares have been redeemed with a large part of those remaining outstanding being unable or unwilling to participate in reaching closure."
That's aside from the option of getting a new manager which clearly isn't an option here. Moving to a different exchange wasn't covered in the contract - but if that proves easy to do then I'll certainly consider it, even if only to let existing shares run their natural course.
At present everything will continue as normal in terms of dividends etc - just there'll be no trading of PURCHASE and no redemptions. Swaps of PURCHASE for MINING+SELLING will still be allowed.
There's no need to resolve it today - and no way I can anyway as I need to find out what's happening with the CIPHERMINE bonds, see what options are available and get as much feedback as possible.
