ETF vs Robinhood Crypto

I know all the pros and cons of both the ETF and self custody. However, robinhood crypto is not really self custody since its not in my own wallet. I would just be keeping it on the app, I have no interest in getting a wallet. I was wondering if anyone has experience with both ways, and if there really is a concern about theft or fraud via robinhood crypto. Has anyone actually had their crypto stolen from their robinhood account? Also, if someone is able to get your robinhood account info, they could sell the ETF and withdraw the money im assuming? Wouldn't it be the same as them stealing the crypto from robinhood? I currently have some in both versions and im looking to just consolidate everything into one or the other. Thanks in advance!
