This is my work I own the channel Mystery History on YouTube, I often cite my online sources in links at the bottom of the description, you wont get any legitimate claims of copyright, or plagiarism as I am the sole owner/creator of all the videos embedded, and if I post something (typewise) which is not mine I cite accordingly, I have also linked my YouTube channel with this channel on my YouTubes main page there is a link which will bring you to this steemit page.
heres a link to my page: https://www.youtube.com/mysteryhistory
