Not that I am a stunt person, but as far as I know:
- training (there are ways to fall that are more controlled and less harmful)
- hidden safety gear (thick clothing, hidden protection)
- hidden set safety (fake floors that are soft, mattresses that are removed in post, etc)
- and finally, getting actually hurt, a lot... All stunt people get hurt often, it is an actually dangerous job
You are mistaken. Sure, bitcoin is like that, but there are alternatives.
Monero is private and anonymous, and its not the only one.
