dont buy at bittrex at the moment, its so much more expensive there. Buy at Kraken instead, as soon as transfers are possible, the price on both exchanges will be the same. You can also compare the prices of the different exchanges here and pick the cheapest - its bitfinex and viabtc at the moment:

But also take into account that the current surge may not be sustainable as soon as all the BCC from cold storage join the market.
This warning apply for every new Bitcoin wallet, we can't be sure that this software is bug free but what I'm refering to it's the term "secure" associated with a drama that some peoples claimed that the developpers of Electron Cash made this wallet to steal bitcoins but that's wrong, you have the full control of your account and this program will not steal your BTC because the files are the same as the compiled version of the source code and lot's of developpers reviewed the source code (https://github.com/fyookball/electrum).
The best way to stay away from potential bugs is to move your BTC to another account before importing your inital account to a Bitcoin Cash wallet (advices taken from this statement: https://electrum.org/bcc2.txt).
