Early this morning on Twitter, Coinbase's "exchange" GDAX announced they will temporarily maintain sole custody of the Classic portion of their Ether huffers' forked tokens for several weeks. The exchange released an announcement:

100% of ETC associated with ETH balances at the time of the hard fork are secured in GDAX cold storage.

We plan to allow withdrawal of an amount of ETC that corresponds to ETH balances at the time of the hard fork. We'll be working on this feature over the coming weeks and will provide updates via this Twitter account.

The freeze has some users on social media wondering if early post fork shenanigans at Coinbase might have threatened the firm's solvency. Sorry fork, your loss.
