My best colleagues, the people I most deeply respect and the people who inspired me to work in this industry all neglect bug bounties. They mostly don't participate in them at all. Bug bounties are usually pursued by people who have the free time and bandwidth for them. For the most part, most security consultants and engineers do not actually engage in them because they are already highly paid. This is why you most frequently see bug bounty participants from countries other than the United States and Western Europe.
Those that do have a full-time position and also engage in bug bounties certainly have a commendable passion for the work (or sometimes more accurately a workable formula for getting to low hanging fruit in new programs first), but please don't expect all or even most skilled security talent to adhere to this rule. Many people enjoy being skilled without sacrificing work-life balance. Just as not every software engineer needs to contribute to open source or have a GitHub profile, not every security engineer needs to have badgers for every company they've hacked.
The folks at Attrition tend to cover it a bit more when it comes to "security rockstars":
How do you get started breaking shit? Github has tons of shit. Go break it. More interested in hardware? Go buy some crappy iot gear and break it. Vulns are not rare and they do not require a damn piece of paper to find. Find them, and you will have no problem finding jobs.
If you are reading this and still don't know where to start, I am happy to help you find things to break and suggest approaches that might help. But seriously,don't waste your time and money getting certified. I don't care at all.
