I think it's a simpler scam
And I'm sure of that because they want Bitcoin ATMs specifically.
Scams work in small steps.
Right now, the instruction is to go out and take photos of the ATM machines and gather data. They have no real interest in the data; it's just busy-work to build up your confidence.
Later, the instruction will be to deposit cash into the ATM, to confirm that the ATM machine is functioning. Cash will be sent to the scammer's Bitcoin account, of course.
The source of this cash will be the cashier's check or bank transfer they will send you, which covers both your salary and the "test deposits".
They may "accidentally" send you too much money; but since you're making test deposits anyway, just return the excess money that way.
This is a remix of the classic overpayment scam: they send you "too much money" and have you send some of it back. They send you the money via a reversible method (fake cashier's check; bank transfer) then have you send the money back via an irreversible method such as Western Union or ... ... wait for it ...
Usually that reversible payment to you reverses, and you wind up holding the bag. But sometimes the payment is valid currency but is tainted because it traces back to a crime; you just helped them launder that money. Same difference in the end; authorities catch up with you and seize the money back.
So right now, you're in phase 1 of the scam: the task to simply find, test and photograph the ATM machine is to get you comfortable with the idea of manipulating the machine as part of your 'employment'. So it will seem perfectly natural to subsequently deposit money into the scammer's account with it.
The money they send you will reverse or bounce, of course; you will be out the money you sent onward; that's the root of the scam.
Why don't I think it's a "case the joint for a bricks-and-mortar ATM robber" job? Real simple: they are wildly different criminal specialties. One gang lives 30 miles from you and is good at chaining ATM machines to stolen pickup trucks. That's not the same skill as making contacts with you anonymously so it can't be traced back to them. That skill more closely aligns with the skill of getting you bogus money that appears real. The sticky point for these scams has always been finding a stable, irreversible way to get you to send the extra money back; Bitcoin ATMs solve that nicely.
The other thing is, the pickup-truck gang (or the skimmer gang) would take many, many ATMs - there'd be no reason to have you drive right past 20 ATM machines at gas stations, pubs, and convenience stores to get to a Bitcoin ATM, specifically. I feel that alone proves my point. Besides, installing a skimmer or hauling off an ATM requires local people, and if they had local people, they wouldn't need you.
