Have you just started your #bugbounty journey? Are you new to bug bounty and is still trying to find and report your first bug to platforms like HackerOne / Bugcrowd / YesWeHack / Intigriti or others?
I’d suggest you try to stay focus on a single bug class instead of trying to become an expert in everything, everywhere all at once!
This is the bug which I focused on in the past when I started my bug bounty journey and I think they are a great type of bug class to find for bug bounty beginners who are starting out!
