We can see coins on bittrex, but is the trading already going on there?
In latest update bittrex cleared his position on this fork they will credit the members account but won't open this market for trading. You can trade on tradesatoshi this is the only which support this at the moment.
It's a pity on the Bitrex will not be able to trade, the Kucoin, too, has not yet decided if I'm not mistaken. Tradesatoshi is not enough for the project BTCP.
RIP BTCP. Now we are going on 25$
