None of the other PR skins have a policy against withdrawing your deposit before clearing a bonus (though 1 or 2 have a WR to withdraw) and Eurobet didn't when it was still a PP skin so I'd say you're safe. Given how long the bonus has been out there and how frequently bonus whores recycle their bankrolls I'm about 99% sure I would have come across a whore complaint by now if Eurobet were taking bonuses back.
