More Steem power only increases your payouts if you are upvoting your own content. Just holding Steem doesn’t increase payouts. I think bloggers who do this for a living would cash out. I was also amazed at how much you tube pays. I think you can make way more money on YouTube (obviously depends on views) so if you are a popular vlogger it prob pays to put videos on YouTube, then advertise them on steemit and get paid twice potentially.
