After making a bKash deposit to bt21, funds are normally credited to your account within just a few minutes. The deposit process is fully automated. Occasionally, network delays may mean it takes 10–15 minutes. If more than 15 minutes pass, let us know via live chat and we will resolve it quickly.

Bonuses & Promotions
Questions about Bonuses & Promotions
Details on welcome bonus, wagering requirements, cashback, and VIP benefits.
After opening a new account, a 100% welcome bonus up to ৳5,000 will be added to your balance automatically on your first deposit. That means if you deposit ৳5,000, you start playing with ৳10,000 in total. No code is needed to claim the bonus.
The wagering requirement for the welcome bonus is 25x. That means if you receive a ৳1,000 bonus, you must place a total of ৳25,000 (1,000 × 25) in bets before you can withdraw. These bets can be placed gradually across any game — not all at once. You can track your progress toward completing the requirement in the bonus section of your account.
