Once CHC starts trading on Bittrex, it will be game over. Here's why:

The main reason why the CHC community (up till late yesterday) has been able to (artificially) keep the price up, is that its 24h volume is pretty low and it only trades on Cryptopia.

Now, if you have a decent community, these circumstances make it possible to, at least temporarily, pump up the price of a coin. But this can't go on for long, even if the coin would keep trading on Cryptopia exclusively. To keep the price up, people must keep buying. But, eventually, people will run out of cash and/or the desire to put more funds into CHC and then the "buy walls" will come down (hard and fast) and so will the price. Keep in mind that "buy walls" to support a price (in a downward trending environment) implies that someone pays the prices (and gets screwed). No-one will endure this long.

If the coin does start trading on Bittrex, it means more (potential) buyers, but also, more selling pressure. Hence, more need for buy walls. But where will these come from? Who will want to put up funds for that? Given the size of Bittrex the 24h volume will increase significantly and the community will no longer be able to control/manipulate the price, i.e. to timely cast up buy walls. Moreover, they'd need to spread/allocate their attention and funds across to exchanges then. And the "community" would grow in a way that it'll be no longer possible to keep everyone within check. I mean: not everyone will want to HODL and buy more to pump the price.

I may be totally off, but my view is: if CHC starts trading on Bittrex, it'll be dead before you know it.
