Why do I need to transfer my BTC before loading my private key to my BCC wallet? Im quite sure loading the private keys will not affect my BTC.
It's to protect your BTC in case the BCH wallet you choose is "bad"
For instance, you just import your current private keys from BTC to BCH wallet... BCH wallet is bad and sends your keys to BadGuy... BadGuy can now steal both your BCH
AND your BTC...
If you send BTC to a new wallet... and import your OldKeys to BCH wallet and BCH is bad... BadGuy can only steal your BCH.
