You must think about this... ETH can only pump 1.5X, but ETC can pump 15X. So whos the winner? ETC will win this battle.
It's certainly a possibility for the exact reason you state. It all depends on if enough people with enough BTC and mining resources see ETC as the money maker in the long term.
I see ETH dumping in the next days, not a lot but maybe to the 0.015 levels and ETC getting strong day by day. By now, the worst you can do, is put money on ETH and holding that falling
knife.
