By the way, recently I saw that there is a content creator who often talks about security vulnerabilities, and it seems that he even opens classes or courses for anyone about it. And I also saw that he said there are so many job opportunities about it, but even though you get a certificate after completing the course, they don't guarantee a job spot, it seems strange.
This seems interesting a course for security vulnerabilities. Id hope to learn this kind of stuff as well. Definitely a lot of jobs for that especially in crypto. Many projects pays huge for this kind of expertise. But since its hard to implement, the payment of this is probably huge and outstanding.
Gonna watch the youtube and finds out about this. Will get a feedback later.
