If you are having trouble finding updates regarding the status of GDAX and Coinbase's proposed compensation plan for ETC it has been holding, it's because there haven't been any since the announcements since July 26 and August 4, respectively. There have been lots of goings-on in the time since, however.
Yesterday, August 12, Gemini announced that they are now offering a one time, lump sum withdrawal of ETC similar to what was proposed by GDAX and Coinbase. Hopefully, this indicates that an announcement is coming within the next few days from Coinbase.
The Whitehat group reemerged and moved around a lot of ether to Poloniex and Kraken, exchanges that support withdrawal of ETC. This caught the attention of the ethereum and classic communities, even sparked threats of legal action from some large DAO investors. They had apparently planned to transfer the funds to a more stable form of currency, presumably forked-ethereum (ETH), and come up with some sort of smart contract to refund former DAO token holders. A large swath of commenters dissented proposing instead that they were trying to steal away millions in ETC and possibly even sabotage the project altogether. The Whitehat group then backtracked and is in the process of asking the exchanges to return the funds.
Then there was the Bitfinex bitcoin hack on August 2nd, in which $75 worth of bitcoin was stolen from the exchange, the exchange announced losses would be shared proportionately across all users and all users would be issued BFX tokens, which might later be redeemed for value or possibly stock in iFinex Inc., Bitfinex's parent company.
These recent developments, and Coinbase/GDAX remaining relatively mum on the topic, raise a few interesting questions: (1) GDAX has it's ETC holdings cold-stored (offline) and is surely being especially cautious in light of the recent Bitfinex hack, but if they can't find a secure way to issue ETC will they opt to do something like BFX tokens?; (2) would they consider something like the Whitehat group was trying to do and issue refunds in the equivalent amount of ETH?; (3) since they have "no plans" to support ETC trading in the future, are they stalling until the market is flooded or the currency crashes and burns for some other reason?; finally, (4) do they have some sort of involvement with the Whitehat group?
TL;DR--No word yet on when or what is getting returned to pre-fork account holders.
Thanks for reading.
