Is It WORTH Uploading In 4K? Mr. Beast Doesn't... 1080p VS 4k for YouTube

I've spent SO much money just to shoot my YouTube videos in 4k but is it really worth it? Mr. Beast, the best YouTuber on the planet uploads all of his videos in 1080p... why am I spending so much extra money on gear I can't really afford if it doesn't even matter anyways... or does it? In this video I talk about the positives of 4k, the negatives, and whether or not it is worth investing and uploading in.
