Countries like the Netherlands, Czech Republic or Malta all have a somewhat modest domestic market but important prop firms( Optiver and all the options MM in Amsterdam, RSJ in Prag...) trading around the world and bringing back foreign currencies home. These are the countries that have the most to lose if the tax is applied based on domicile. These prop firms would relocate and restart activty elsewhere one month later, end of story. They wouldn't even have to think about it.What is RSJ profit margin with all the crossed trades? 0.0005 %( 50 cents per 100000 Euros )? Good luck trying to make them pay 0.01%...
