I have seen some casino setting up huge wagering requirements for players which can be problem for small gambler but in duelbits past giveaways there was 1x wagering requirements which was easily claimed by small gambler like us.But if there are say more requirements then small gambler don't participate in them.
Have you ever taken part in a promotion every Friday from duelbits which gives cashback deposits of around 30%? If I'm not mistaken the wager requirement is only the value of the deposit made and the player will get the bonus, 1x wager requirement is not a difficult amount to fulfill and even when you have done it the player still has the opportunity to profited from the bonus, but last Friday I no longer got this promotional email, maybe duelbits is planning a different promotion.
