The "bcash" term is used to attack BCH. It makes many of the attackers (that are everywhere on social media) pretty easy to recognize. Dishonesty and personal attacks are their "bread and butter". They attack BCH because it is the only Bitcoin still working to allow massive scaling.

Dark forces captured BTC to stop it from becoming a real peer-to-peer electronic cash for the world's people. BCH is keeping that dream alive and the dark forces opposed to financial freedom have been attacking BCH since before it existed.

I am sure there are BTC and BCH wallets that can steal your private keys. Don't use a wallet from an unreliable source for any crypto.
