This is how I split my coins. May help if you dont have android.
I started with my BTC on an Electrum wallet.
- Sent my BTC to another wallet, in my case Bread Wallet on my iPhone. My Electrum wallet now showed a 0 balance of BTC.
- uninstalled Electrum and installed Electrum Cash wallet. The config files were still all there, so it immediately showed a balance of BCC. I didn't even have to recover using secret phrase.
- Sent the BCC to Bittrex.
- Waited 24 hours and sold it for .0977! (YMMV on price)
