I've never checked my own content for plagiarism for the obvious reason that I don't need to. Why don't I need to? The reason is also obvious - because I write my own content.
So why do you feel the need to run your content through a plagiarism checker? (A rhetorical question which doesn't require an answer.)
A simple rule for you to follow - if you're pressing "CTRL+C" followed by "CTRL+V", then you're plagiarising. Even if you use "Translate to English" first or "Make it Unique" after.
Just delete all of your posts about crypto. I know that you didn't write any of them so I'd like to see them all gone.
