Arguments for 5bil:
Bounty posters can at least do 5 symbols
and Akainu being the highest ranking marine, it's logical his bounty uses up all 5 spaces with the highest symbol (π) and get the maximum possible bounty = 5π
The bounty system is the same as Dressrosa's.
Despite Admirals having 3π it doesn't mean that the next highest has to be 4π
Oda can jump from 3 to 5 symbols no problem
Arguments for 4bil:
1. Cross Guild is not rich enough for 5bil
2. "Above Yonko range" lol
