I like no. 2. option

My friends and I are 3rd, 4th, and me 5th respectively. I can be 3rd place if I change my teams to beat him specifically.

Anyway. 1st, 2nd and 3rd are pretty much equally power they should have given them equal coins. I think that's the best solution.

My friends and I used to beat each other on the last min before they gave out coins, now we don't really care. Too much effort.

Option 7 is also nice, BUT Rank 1 won't be able to do his Monthly Event then if that comes back. Or is it there still next week? I have not yet looked at.
