Yes and no.
It really depends on your channel, and if you can keep the content of consistent quality.
Last 2 years I did a daily upload between xmas and new year. First-year i did gain views, but hardly any subs.
I did cut some corners here and there, so not all content was as high quality as it should be.
Last year i did a good and consistent upload, again xmas till new year. Roughly same increase and views, but i gained more in subs. Better content, better result.
This year i'm gonna do streak number 3, xmas till new year.
I know of a fellow motovlogger who is doing Dec 1 till xmas day, daily uploads.
But he does a more face in screen style vlog, so for some people they feel more connected.
His views and subs rise is huge compared to before.
So it can be worth it... But it is a huge amount of work
