On the other hand, I heard few Ministers (of Bangladesh) are holding around 100BTC (per head). And, they are very bullish on BTC.

India is old school and up to now has been taking extreme measures in dealing with cryptocurrency. Cryptocurrency give those who are poverty stricken a second chance especially those who depend on the Crypto bounties to make income just to survive. What nay seem like peanuts to some, may feed a whole family within an impoverished country. It is good to see people in India taking the high road to get regulations pushed so that the law becomes easier to navigate. Some countries aren't as quick to reach a compromise.
  I think fear and uncertainty is what drives governments into throwing ban hammers at crypto being it's easy to outlaw it and then figure out the details then to just let things be. It is stifling to creativity and hurts the peoples pockets. Hopefully governments work with the people to make guidance much clearer.

It will be a great news if Bangladesh lifts the ban on bitcoin because it will be a wild market for bitcoin as most of the people is south Asian nations are well versed with bitcoin and crypto unlike other part of the world and definitely they will contribute in a positive way to the world of crypto but we cannot celebrate just with the news of blockchain legalization by Bangladesh government as they can use it in banking sectors or adopt a centralized crypto such as ripple by still placing the ban on bitcoin, blockchain is a vast technology which crypto uses and other non crypto domains does use blockchain.

Even if the country revokes the ban on bitcoin it's people should also support it instead of scamming or using it for wrong purpose.

From all that you've mentioned it looks like Bangladesh is moving forward with something positive about the blockchain technology. This needs to get legal usage access for bitcoin, there are countries where blockchain usage is found high while they've got restrictions on cryptocurrency usage. Anyhow acceptance of blockchain technology itself a big recognition for people who have been facing hard days of arrest and other hard punishments for using bitcoin.

It's about the blockchain technology itself not cryptocurrency is what they are interested about. They knew blockchain can help them for banking solutions. Even China promotes the use of this technology. I think they are going to create their new blockchain. But no news about removing ban of the country. Hope the government will unban the use of cryptocurrency there. So people will enjoy the benefits of cryptocurrency. Hope they make a big announcement soon.

Nothing said about adoption of Bitcoin but adopting blockchain as their financial system. Just like China, they are likely to develop their own blockchain. I don't know if it will create hype on market. But still a good thing because they appreciate the use blockchain technology for a better financial governance. I'm not hoping they will unban cryptocurrency there.

I see many countries are ready to accept innovative technology and revolutionary platform for better businesses and governance.

But due to corruption, centralized government, and lack of knowledge about blockchain technology and its environment many countries are still in confusion, even depends upon other developed countries.

But my honest suggestion is don't play with common persons right.

As Bitcoin and other altcoins are open source, so the government has no right to ban or make any legal clause for them, its because if any government cannot control its supply, cannot produce it, and even cannot decide its price then who gives rights to make law for them. May poor countries including India, Bangladesh, and few other Asian countries are misleading to their users by giving false information. And there are no willings to adopt technology for the future.

Blockchain =/= Bitcoin.

If they stated they are going to make it legal then they even don't know what is that,there is no need of legality from government to use it.

Although it does provide publicity to blockchain, the core technology of bitcoin, it wouldn't affect the market as much. These governments adoption, even China, only focuses on the blockchain and not on the bitcoin. They're making their own cryptocurrencies to mitigate bitcoin's popularity since they don't want any decentralization, or power to the people. However, they're more or less likely to succeed though, they're just adding to the crowded altcoin market. However though, it's backed by the government so people may tend to use it especially those new to crypto.

And we can't really do as much since blockchain is not from bitcoin, it's idea and technology is invented way back before bitcoin is made.
