Sweden has similar money laundering laws as most other countries. Any amount over 10k euros (or structured as such) is tracked and reported by the casino

under 10k they're not going to bother but if you have a big score it will be reported.
so, they operate more or less the same as the usa.
most money laundering laws are international agreements anyway
I can't just say 100k cash is a casino winning and absolve myself from any investigation or relevant reporting.
but if i take that money to a casino over time, exchange for chips, and either turn it over or cash it out all at once, I can attempt to plausibly say it's gambling winnings, as the casino will have that amount reported. Yes, even in Sweden, that amount is reported
