So I had my bitcoins in electrum wallet when the Bitcoin cash fork happened. Then I moved my btc to bittrex and back few times. Now btc are in bittrex. My question is what should I do to retrieve my bitcoin cash? If someone could explain to me step by step becauce now I am a bit lost. Do i need to transfer btc from bittrex somewhere? Or can i create electron wallet with a seed at thats it?(I tried to retrieve eletrcon wallet with a seed but could not press 'next').
