@whatsup There are a few reasons for holding STEEM POWER:
- Receiving interest (15% of all created STEEM goes to STEEM POWER), which currently is ~1.4% (15% of ~9.3%)
- The ability to earn curation rewards, which easily will get you 10% ROI per year
- Having more power on your curation actions (if you just like supporting the network)
1 - Yes
2 - I don't vote for curation as I wish to support accounts that others are missing due to their bot activities.
3 - possible unless those who feel the need to tell everyone else how to use their stake make it impossible to enjoy the site while retaining a high level of Steem Power.
I don't know what you mean with your second point.
Regarding your 3rd point, just do what you think is justified. If you think you're doing what's right, then there is no problem (unless it's considered abusive by others). I'm sure you enjoy doing good curation work.
