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.
That's great to hear! Right now i can say i have heard about 10 countries who are opening up to the adoption of blockchain technology and cryptocurrencies which is good for the start. What's is really left is for the big countries like the US, UK to also announce their interest. Just recently China has shown some slight interest which really affected the marekt to some extent.
Sorry about your loss mate but most of us have also been scammed before. Also, if you still have evidence about these guys scamming you then i think you can take them on once cryptocurrencies is approved in your country.
