Hi. Firstly - apologies if this has been asked many times before. I searched but came up empty.

I have some BTC stored locally. I want to cash out a portion by sending to an online exchange. But I don't know what to do regards BCH. Is it safe to send BTC to an online wallet using Bitcoin Core client? If I do this will BCH also be sent to the online wallet, or retained by me, or lost?

Any advice or pointers to article appreceiated.
