7 and 8 for me. Personally, I'm a big fan of leasing as did it with HIVE and it's been really nice to just be in the knowledge you'll have the same amount coming in each day with the stake leased out at a given APR.

With a bigger stake you can also get a team of curators that can reward authors that may have gone unnoticed or support comments in line with Leo's initiatives too to help growth. Just throwing ideas out there but those would be my top 2.

Number 2 could also be fruitful but I'm not really sure about how liquidity pools and all that work!
