I strongly believe the Bangladesh government should know better. I hope they realise soon, just like the Vice-president of Nigeria, that bitcoin and cryptocurrencies at large is the goose that lays the golden egg.
I hope they will realise soon enough that they have been going in the opposite direction while world is moving forward. They should know that usage of bitcoin in a country can help improve the economy of such country and this is exactly what it is needed in a country like Bangladesh.
When they find a way to tax it they will approve it! It's how I see it! Simply third-world countries (and I believe I live in a third-world country) don't have the infrastructure to do more complicated tasks, so they don't know what to do with crypto! Of course, there's one more thing... stupidity! Most people who sit on the top are old, conservative, narrowminded... call them as you like! They don't know how to turn on the smartphone, how can we expect them to understand crypto?!
But times are changing... and change will happen in all countries, sooner or later! Younger generations are taking over and we are more digitally oriented! I guess for some countries, and people who live in those countries, hard times are coming! Transition is not so simple for all! While some are going through that without problems and casualties, others pay a lot higher price!
