How to make money in Watch Dogs 2?

Unlike Followers, you won't get cash for completing missions (aside from any Money Bags or other pick-ups you find along the way). Instead, you'll collect it little-by-little from exploring the world in various ways, or taking part in specific open-world activities.

Exploit to get $18,000 every 40 seconds - The fastest way to get money that we know of is courtesy of a technique by WikiGameGuides on YouTube. This has you replay a section within the 'A Real Dog Fight' in the "Eye for an Eye' mission, that has you hack a certain person for $18,000, reload a checkpoint and repeat. The technique is explained in the following video:

Pawn Shops - As you explore the world and break into cars, you'll loot valuable items. Pop into a Pawn Shop from time to time - they are located on the Nudle map - to sell these for a little top up.

Money Bags - As well as Research Points and Key Data, you'll occasionally locate Money Bags nearby by using the NetHack vision (click in the right stick on a console to activate). These tend to give you around $5,000 a pop, but are usually located in restricted areas guarded by enemies. If you're able to get in and out quickly, they're not a bad time investment - especially if you use a Jumper or Quadcopter.
