It's getting dangerous to go out with your smartphone where you have installed a crypto wallet or an exchange application. It's better to walk with a smartphone where there is no trace of you having a crypto.
I agree! There should be, ideally, no way to access crypto directly from your smartphone. I know this will upset some Bitcoin purists who want Bitcoin to be used for everyday transactions, but these kidnappings are showing some real dangers to openly using Bitcoin. Uncensored and irreversible transactions are ripe to be a crime magnet - it's just not worth it from the standpoint of personal safety.
I can't say I blame people who store crypto in a way that makes it impossible for kidnappers to steal it - this means it's stored in a way that makes everyday purchases impossible. In other words, the seed phrases are nowhere near the person kidnapped, completely inaccessible, and he has no recollection what it is. So the kidnappers end up empty-handed with the police looking for them.
