How can I claim my BCH?

Hello folks.

I got into BTC back in 2015, never sold it. It's in the same wallet since then.
So, how did you claim your BCH?
I've read about the exodus wallet. But I didn't make a move

I wanna claim my BCH, because I think it will rise in price in the next year....
Is it safe to share my private key with this wallet?
Can anybody gimme a hand?
