Folk please be understand about current problem, not only Kraken and Bittrex,other site also did this because they're doing a maintenance for Bitcoin Cash. So,if you're using an exchanger or website or whatever and they are supporting Bitcoin Cash (BCC/BCH) more likely they are doing a maintenance. But i can access it today by the way,so it might be only a temporary maintenance because 11 hours ago i logged in. So just stay cool folks,it will only take a little time for them to do a maintenance.
I am a member of Bittrex and they have already credited my account with my little share of Bitcoin Cash but the wallet is on maintenance until now so that means nobody can sell nor buy Bitcoin Cash for now...we have to wait for it to go live and then we can start dumping the coin to our desire. The real Bitcoin is also having its own maintenance so both coins are still not accessible in the exchange. However, I am already happy that I got my share of the free coin BCH. Good thing I transferred some of Bitcoin to Bittrex otherwise I would not have my own BCH.
