I was one of those people that said Marco's bounty will be higher than Luffy's.
Now I won't commit the same mistake again.
If Oda based his bounty based off significance events and number puns then I could see King's bounty being at 1.4 or higher than 1.5
But since Oda is a troll, I could see King's bounty at 1.33 bil (which is the one that I'm going with).
And if King's bounty is lower than Queen's, I would be on the floor.
