If I were the government, I wouldn't make it illegal and jusy regulate it instead. That way, the government still grows and revenue is harvested from the movement of bitcoins. Maybe that's the reason why governements are still studyinh bitcoins, to actually make money out of it. Sly sly government.

The government is having a hard time tracing bitcoin because it is untraceable. Another reason is because it costs so much, it takes great effort for a government to remove a commodity of great value from the market. It'll cause chaos and will most likely cause major fallouts in the digital world. Finally, I think as well as most people here, that the government actually is trying to make some sort of a money making scheme from bitcoins that's why no one still is taking an effort to ban bitcoins after China.

At one time, Bitcoin will prove to everyone how useful it is to us. This is illegal in many countries. But many countries make it legal. They love Bitcoin. Their country started as a legal currency. So we think that soon Bitcoin is going to be introduced as the legal currency of other countries. Bitcoin has a bright future. It will not be destroyed.

Bitcoin is not a threat to everyone, instead it could give us a new start in living with digital currencies aside from existing fiat money. Russia and China are very supportive to crypto at first and having large numbers of miners and investors are from them. We can't really point out of what is the big reason of leaving crypto in their country but all of this, it doesn't give a huge impact of bitcoin life in the market .

because they have some reasons thats why its illegal number one reason is bitcoin is not traceable illegal transaction will made if they cant fix it. they will use bitcoin as a payment for their drugs and other illegal things. lot of people use bitcoin to hack other holders and make an scamming sites to earn more money.

Dubai is currently in the process of banning Bitcoin so theres currently 4 countries that are banning countries.

Very interesting. I shall examine.

you can't really ban BTC, it's very difficult and i'm pretty sure it some country would ban bitcoin we will always find a way to keep supporting this project.
Regulating? is not possible due to decentralisation, again they might find a way to regulate (to give them advantages, don't be fooled they'll regulate for you) but everything will stay the same anyway.

I do not know exactly but here in our country, when you want to buy bitcoin or use bitcoin to pay your bills, you can pay it through banks.  And there is no reason for our government to make bitcoin illegal.  It can contribute to economy of the country because of the extra service or fees bitcoin can give. 

i think its fully possible for a government to shut down bitcoin entirely, it's just a matter of how much theyre willing to dedicate to the effort in terms of resources. iirc, law enforcement was able to pinpoint illegal TOR based sites (not that TOR is illegal itself, but sites such as drug exchanges, child porn, stuff of that nature) by tracking ip response times and other factors (it's been a while since i've read thsi, wish i remembered it more clearly). in addition, bitcoin has an inherent weakness to the dedication of excessive resources: the 51% attack. if a government was willing to actually dedicate the resources to set this up, they could effectively start reversing transactions and manipulating the network to their means, which could lead to the death of bitcoin. at this point, they wouldnt even need to outlaw it, they would control it.
