If you don't make auto posts, I personally have no reason to downvote you.
As for profiting from delegation, leasing is more expensive than curation, it's just how it is, if it wasn't it would be massively exploited.
To put things in perspective, a good curator who is active and don't let their VP go to 100% will see about 7.5-8.5% APR for curation rewards. In addition to that, if you own the Hive Power (rather than lease) you will get about 2.8% in addition in interest on your Hive Power.
The only way to profitably curate is to own the Hive Power or get a free delegation or massively reduced price, but this is very difficult and highly unlikely.
Renting Hive Power is typically only done to support a community at a loss. There is no way around that fact, leasing is expensive and curation rewards are almost always less.
Thank you, I will consider what you said.
