As of 9pm EST, Wednesday, here's the price of BCC/BCH at different exchanges:
Bittrex: $825
Kraken: $487
Bitfinex: $402
Why the Huge Differences?
Since we can't move BCC/BCH around yet, each exchange's BCC/BCH sellers have to be drawn exclusively from its own depositors.
But here's the thing: the average depositor at Bittrex is a very different person from the average depositor at Bitfinex. Specifically, Bittrex is a site you deposit at when you're interested mainly in alt coins, since it trades about a hundred of them. Bitfinex, on the other hand, is more for folks interested only in BTC.
Since those two pools of sellers can't yet mix, it's led to massive price differences.
How do I make money at Bittrex?
OK, so from a strategy perspective -- subject to all the usual 'none of us can predict crypto' warnings -- if you hold any BCC at Bittrex, you should sell it, because you're currently isolated in a market populated by alts loving BCC owners, comparatively few of which are willing to sell their BCC versus, say, Bitfinex, which has led to an artificially inflated price at Bittrex. But that situation won't last. As soon as we're able to move BCC/BCH between the exchanges, expect the price to fall as people with BCC at other exchanges move it to Bittrex to sell for the higher price.
In other words, BCC supply will finally be allowed to increase to meet demand.
EDIT: Even if you're an absolute supporter of BCC, you should still sell all you have at Bittrex for BTC, then move that BTC to Bitfinex where you can buy back basically twice as much BCC (renamed BCH there) as you just had. Double your holdings, for free. Only in the crypto-verse......
OK, But I'm at Bitfinex / Kraken, is the Converse True?
So is the price of BCH likely to go up at Bitfinex / Kraken? Should I be buying? Maybe, but there's two things to remember:
1. The correlation isn't as strong because an alt crazed Bittrex depositor already can, and probably already is, moving his BTC to Bitfinex to buy BCH more cheaply than he can on his 'home' exchange.
2. There's a bunch of would-be sellers that are currently locked out of the exchanges: big, institutional owners of BCH like Coinbase/GDAX/Bitstamp and sportsbooks like Nitro/Cloudbet, etc.; plus, all the little guys who had their BTC in private wallets during the hard fork. Some (most?) of them will want to sell, but can't yet transfer their BCC to an exchange to get that done. At some point soon, that will change and a bunch of sell side shares will hit the exchange markets, (possibly?) reducing BCC's price.
Good Luck to All!
