I just saw a news that yesterday Brac Bank Talking about blockchain technology and they also working to legal blockchain technology.Maybe this is the first time any Bank in Bangladesh talking about blockchain.Though few months ago Bangladeshi PM told that blockchain technology will be legal soon.Now just waiting for confirmation that bitcoin (blockchain) is accepted.Because we faced many problem to use btc,even few people arrested.also in 2018 one people scammed me 4-5.5K$ worth of crypto currency.who live in Bangladesh. Even he scammed maybe more than 300k$ from 20-30 peoples.Though i have all kind of proof but i didnt take any steps because crypto is illegal.I didn't take any steps.because police can arrest me for using bitcoin.

They may accept and adopt the technology behind bitcoin, but it doesn't mean that they are going to accept bitcoin as well. So I don't think that they will change their hard line stance against bitcoin here. The government may just want to harness blockchain for their own good.
You can see this discussion in the Legal board as well,
Bitcoin Bangladesh.
