What kind of business with ATMs "takes the money home"?
Even if it's totally legit, it's also totally insecure - they could be robbed at any time.
Money in such quantities are not takes to the home and stacked the kitchen top, they are deposited to banks - by armored guards in vans.
The kind where $200M of customers' money "goes missing" and the ceo "suddenly dies" on a holiday to a country famous for its scam artists?
Whereas the parent commented that "they might had simply taken the money from the ATMs home" as an excuse for them being a legit business while having stacks of cash on their kitchen tops.
Definitely not ideal, but what else can they do?
The issues at the beginning was use of non-standard sized bill receptors and non-digital vaults at the ATMs but that has been solved recently. At the time, we used two ideas: provide a regular ATM right next to the Bitcoin ATM to dispense bills out (so we'd get ACH) and regular pickups and drop-offs to a bank.
Unbanked businesses? Some of them because they are illicit, but others exist because banks don’t want the association.
