Exploit prices are rising

Apple offers up to $200K "for major flaws in iOS".

Exodus offers up to $500K for the same.

Probably there is a marketing catch in "up to".

Likely on the black market prices are higher.

IIRC Some leaked Hacking Team emails suggest "exploit brokers" are 
reselling sploits for $100K per sploit (and possibly higher).
