no idea about casino but i played poker there for years and yeah they were somewhat (much?) slow when it comes to payouts. At one point it was normal for skrill cashout to take like 10 days, so i stopped playing there a year ago.
not sure how is it past migration though, and i know they had some monetary problems in the past but i suspect migration to bigger poker network (and better casino games) has helped them greatly, but as i said i dont really feel like testing it so... have a free bump for now
oh and while they were never the fastest when it comes to payouts, i dont think anyone complained about non payments though. But in todays day and age where cashout at places like
rizk, casumo, mrgreen, trada etc takes anything from couple of minutes to few hours max i dont feel like playing at a place where it takes a week to get your money.
