Can I include the link to another person's youtube channel in a monetized app series?

What is the name of your state (only U.S. law)? MN

Do I need permissions?

(also, this has nothing to do with the guess-the-youtuber series)

You still have copyright issues.

Here is another YouTube link for you to read, this time on "fair use:" https://youtube.com/yt/copyright/fair-use.html#yt-copyright-protection

Whenever you are using material that was created by someone else, there are almost always copyrights to consider. The copyrights held by others especially need to be considered when your plan is to make money off their creative works.

Getting permission from the copyright holder is always going to be the safest route for you to take.
