Bitcoin doesn't remove the risks of you getting mugged. If anything, it's potentially worse with bitcoin/crypto. They just hit you with a wrench at your home until you give up access to your wallet. Hence why being private/secretive about your holdings is very important!
https://cryptosec.info/wrench-attack/The risk is always there no matter if you are talking about bitcoin or any other asset when you are walking on the street there is a chance for your phone to be mugged and there is the same situation for many other things such as the car and physical wallet but regarding bitcoin, since you can save your assets on the wallet you have better chance to hide your private keys or recovery seeds to access your account, and is you leave in bitcoin security you know none can have access to your wallet unless you share your private keys with them which can bring higher security.
