it's the red announcement over the card. the profile box is blurred so we can't read.
マルコの懸賞金はX億XX万ベリー!!
The big problem is :
My translation of this is : Marco's bounty is X billion XX million berries!
But you gave me the 9億99万 . These letters/numbers are your interpretation or really what is write in the picture ?
So on the one hand, a text says his bounty is over a billion, on the other hand, a text says his bounty is under a billion.
It is not clear, we must wait for official confirmation.
Edit : The fact that his bounty is less than 1 billion would not be totally wrong either, it would prove that the power is different from the dangerousness.
Anyway, just, let's wait to get his card in better quality.
Edit 2 :
マルコの懸賞金はX億XX万ベリー : Marco's bounty is X billion XX million berries!
9億99万 : 999,900,000 berrys.
(This second edit is just a comparison between the two japanese texts)
