Imagine if major corporations like mcdonalds or coca-cola got into HIVE and wanted to boost their articles to the top of the trending page every day.
You first need to build the userbase you want to sell it off to corporations. There is a faction betting on building it through relevant content. It could be right or it could be wrong.
Coca-cola talk is daydreaming at this point. But even then, users downvoting Coca-cola promo make them need even more Hive sending the token price even further through the roof. Coca-cola has no feelings to be hurt and can afford to pay the community-requested premium on their ad. You only need to make sure the major frontends do not mute Coca-cola content based on receiving too many downvotes.
I don't think coca-cola is going to be interested in participating unless they can guarantee their placement with the smallest possible investment.
LBRY Odysee.com ranks vids based on staked tokens.
You can stake to your channel and or stake to one or more individual vids.
You can also stake to someone else's channel or to someone else's vids.
This makes staking like an upvote that you can take back later if you wish.
The same goes for text posts and file posts (not just vids).
LBRY Odysee.com also has an option for you to post "pay per view" content.
