I've been using the Melbet app
https://melbetapk.app/ for a few months now and I'm really happy with it. They offer a great selection of cricket matches and other sports, and the odds are pretty competitive. The app is also very user-friendly and easy to navigate. However, it's important to note that online gambling isn't exactly legal in Bangladesh. While Melbet seems accessible, I always use a VPN for extra security.
