About Nadja
Nadja specialised early on in finance and tax law - a field rarely explained as clearly in crypto gambling as it should be. At Filth Casino, she's made it her mission to change that.
For over six years she has tracked every change to German tax law around gambling and cryptocurrencies. Her standard: no clause stays unclear.
She's especially fascinated by how rakeback and clever withdrawal strategies can be combined to genuinely keep more of your winnings - completely legally.
When Nadja isn't analysing new tax rules, she builds calculators and guides that make complex financial topics understandable for every player.
Nadja stays in close contact with other finance and legal experts across the crypto industry to make sure Filth Casino always stays current on tax legislation - not just in Germany, but across the European context too.
Her biggest success: hundreds of readers have used her articles to understand how to genuinely maximize their winnings and rakeback legally - a topic many other sources make far too complicated.
