1. USD CARE

USD CARE is the best and lowest rate dollar exchange in my opinion. They are the official exchange partner of Perfect Money. Also I myself do regular dollar exchange from it. Its service is from 9 am to 11 pm. Moreover, it responds much faster than all other exchanges. There is a direct message contact system if you have any issues.

2. Exchange web money

Exchange web money is a very popular dollar exchange and money transfer website in Bangladesh. There are about 20 wallet exchange options. It has more users than other exchange websites. Its service is from 9 AM to 12 AM. They confirm any customer’s order within 5 to 30 minutes. If you have any problem then there is chat system directly on WhatsApp or website.

5. Trust Exchange BD

In the beginning they used to exchange dollars on Facebook. Now opened a new website and started dollar exchange. They have a good following on Facebook. Their service is from 11 am to 11 pm. Now they are not responding for a month now. So this October I have not received any update from them.
