The bounty will freeze after you become a shichibukai, for example Hancock has a bounty lower thant 100 milion, only because the government instantly recognized her strength and gave her the title. Probably the same happened with Crocodile, remember that he has a logia fruit after all. The fact that the known bounty has gradually increased their value, it's a good story-telling choice in my opinion, he could instantly present a shichibukai's bounty (like Mihawk, if he has one) during the East Blue saga after all.
