If mining of that chain is very low, it will take a long time before the difficulty adjusts downward. So far 6 blocks have been mined on that chain. Rate is maybe one per hour, instead of the usual one every 10 minutes. That puts the difficulty adjustment maybe six weeks out. We'll have to see who mines on that chain. The hash rate may go up or down, depending on what the big miners do. Mining will be unprofitable until the next difficulty adjustment, because the price of the coin is lower than the "mainstream" coin. Confirmations will be really slow. After the next adjustment, the chain will work better.
Something similar happened to some altcoins. Some big miner mined for a while, made some money, ran up the difficulty adjustment way up, and then stopped. Block generation then stalled. This thing self-adjusts, but adjusts to big changes in hash rate very slowly.
Whoever is mining should take about 20% of their capacity off line (presumably devoting it to the other Bitcoin) for a day to force the early hash rate reduction.
After that, BCC should function normally. The financial end is a separate issue; that won't be clear until BCC markets are fully functional.
