Bangladesh is a very unique and complicated market especially when it comes to international payments. There are lots of restrictions when using a Bangladeshi credit card for international transactions, so if you want to accept payment from Bangladesh, you would likely need an alternative. There are a lot of other restrictions in Bangladesh that makes international payments complicated, Bitcoin is also prohibited in the country for example and even PayPal does not offer services there.
