Not what he is saying :D
You borrow the 200 hp for 1 month and earn curation rewards from that, which is max 10%
I do a lot of leasing or have done.
You can literally pay 1 Hive to get 85 hp for 5 weeks. So properly 2 hive for 200 hp for 4 weeks and by doing that, you are not even earning the 2 hive back x)
Promoting for 7 days cost 500 point and has a little engagement if you have not a post with large interest.
I think that the delegation is a good idea, maybe because the old boosting system wasn't susteinable a lot
