We're far worse here in Europe compared to that, it comes at around 6000 euros.
In the EU the limit for cash transactions without having to file extra paperwork where at least one party is a business is set at 15k EUR. Quite a few countries have lower limits but it's not everywhere.
Seriously, who deas every day in cahs with more than 6000 euros?
Used car dealers, money exchange offices, some wholesalers who have customers paying in cash, and many more.
