They may not know how much it can help the poor and unemployed, they do not study about bitcoin, how good is bitcoin and how useful. Should have been thought out first before they can be banned.

Bangladesh, Bolivia, Ecuador, Kyrgyzstan, and Nepal are the top five countries banned bitcoin
Like the ban on drugs, alcohol and the Internet, the ban on Bitcoin is unreasonable and unwarranted, and we hope to have a positive impact on bitcoin.

You are right, the government must have a reason why bitcoin is prohibited in the country, and if the concerns do not occur or are not proven then the probability of bitcoin legality will change.

indeed a lot of countries are still resisting bitcoin, but I myself only know if there is a state that to imprison its people if using bitcoin, it is true bitcoin can be misused for money laundering, but sooner or later if bitcoin is acceptable in all countries is not impossible there is a detection system that can see money laundering action 

Bitcoin in Morocco
Bitcoin and other cryptocurrency transactions were officially outlawed in Morocco in November 2017 seemingly in response to a major Moroccan digital services company, MTDS, announcing a few days prior that it would begin accepting Bitcoin payments.

Sending and receiving payments via any cryptocurrency in Morocco is punishable by fines.

Bitcoin in Bolivia
Cryptocurrencies have never been legal in Bolivia and the government has been known to enforce its anti-Bitcoin stance rather firmly. People caught using Bitcoin and other cryptocurrencies can be fined and a number of users have even been arrested on more than one occasion for trading and mining Bitcoin.

Bitcoin in Ecuador
Ecuador outlawed Bitcoin and other cryptocurrencies in mid-2014 as part of its financial reform plans. The ban on Bitcoin was seen by many as a way to reduce competition with the country's own digital currency system (Sistema de Dinero Electrónico). This official Ecuadorian currency isn't a cryptocurrency and isn't based on blockchain technology. It's simply a digital money solution based on traditional money and valued after the American dollar.
Bitcoin in China
The trading of Bitcoin and other cryptocurrencies was banned in China in September 2017. Due to the technology being so popular in the country before the ban though, the change in law hasn't ceased its use completely and many Chinese people continue to trade cryptocurrencies via in-person trades and chat apps like Telegram and WeChat.

The Chinese government appears to target professional cryptocurrency trading companies over individuals.

Bitcoin in Nepal
Nepal's stance on many aspects of Bitcoin and cryptocurrency is a little ambiguous however it has been confirmed that the trading of Bitcoin is considered illegal following several arrests of Bitcoin traders in 2017 that resulted in a combination of fines and jail terms for those involved. Attempting to use Bitcoin and other cryptocurrencies in Nepal is not recommended.

Do you know? Citizens have flooded the signatures petitioning the President. The pressure on the governing body of the same government began to contradict each other, ending with a formal announcement by the president without any "ban" imminent. Congress of this country has banned the "currency", but "currency" in the same law is defined as money issued by a State, and in Ecuador, it is US dollars. There are a number of newspapers reporting the law as "banned bitcoins", but without any basic principles. So, for me, the most likely explanation is privacy, you can use Bitcoin if you want, but you can not accept it "official" for payments if you run a business. in Ecuador.

It is not that bad as it appears to be because we are having the experience of India that have a desire to overlook those bans that they have put on Bitcoin, and maybe cancel them.

I think that this step was really unwise from their side and they will regret soon and change their mind. i am sure that soon all countries will change to btc and this will happen very soon

honestly i do not understand the reason so forbid bitcoin. I am concerned about this news, hopefully in other countries there are still many who can accept bitcoin. taking into account the potential for bitcoin for the future.
