Cash app is a custodial wallet.

Not your keys not your coin.

I know there has been many custodial wallets that have ran off with people's Bitcoin.

It's not easy to teach people how to secure their own Bitcoin off custodial wallets. Most people can't do it.

I don't know much about that app. I would never keep large amounts in any custodial wallet.

I never gave up. I still tell people but maybe I don't go into depth too much. Just plant a seed.
