One of the main reasons for 4raBet’s popularity is the site’s bonuses, one of which is a 700% crash welcome offer. It matches your first 4 deposits for 100%, 150%, 200%, and 250%. In total, these multipliers will give you up to 40,000 BDT with wagering requirements of x40 (applies only to Aviator and JetX).
You should also consider social media giveaways (subscribe to all 4raBet social and wait for a draw) and promo codes. The last are scattered around the net and give you free BDT or cashback.
