New here - safest way to share research portfolio?

Hi all, I'm Anket - crypto researcher from Lucknow tracking BTC derivatives & infra narratives (non-dev background).

Currently applying for Research Analyst roles. Question: For founders/recruiters, what is the safest format you recommend?

- View-only Google Doc

- Notion public page

- PDF

Also, any red flags I should avoid when sharing my research samples?

Would love feedback on how you structure your research portfolios too. Thanks!
