What about kid and law ? How high do you think their last bounty will be ?
Law will either get 4,500,000,000 or 5,000,000,000 (Ope Ope).
As for Kidd, if Law gets the first cypher (4,5B), he'll get something between 4,700,000,000 and 4,900,000,000.
If Law gets the second cypher (5B), he'll bet something between 5,000,000,000 and 5,015,000,000 (gag for surpassing Law of juts 15,000,000).
In every case, I'm condifent they'll both be at the top od the 4B range or the bottom of the 5B range, with Kidd edging out Law a little bit.
I chose well-rounded numbers for Law cause that's almost always been his case (200,000,000, 500,000,000, 3,000,000,000).
