YouTube reused content

There is some risk if the videos mainly belong to other creators. YouTube may review the channel's overall originality, so translated clips aren't a guaranteed long-term monetization strategy. Original narration, meaningful edits, and permission to use the footage can help, but approval isn't guaranteed.

This is only a temporary way to make money. In the long run, your channel could be penalized or demonetized at any time due to copyright issues.
