i also do not think that it may be possible because there are so many other sites that government have already lock but still people are using the.  so i can say that it many not be possible that government will block bitcoin.

I do not know whether politicians also have their hands on bitcoins. May be secretly they have also bitcoin wallets. Governments always wear a mask in front of its public. If we talk about the blocking of crypto currencies, it can't happen. People use different proxies to break such restrictions.

Bitcoin has no physical location to assault. On the off chance that there we to obstruct every one of the sites that individuals can download Bitcoin wallets from, new ones will come up and a few people will incorporate their own wallets from source code - Bitcoin resembles Bittorrent is that regard.There is no single association or individual that controls Bitcoin and exchanges don't experience a focal clearing house there is truly no chance a controller can prevent individuals from downloading Bitcoin wallets and sending each other bitcoins.  In the event that they close down the web, individuals will send each other Bitcoin through SMS and on the off chance that they close down the power supply, individuals will utilize sun powered and battery-fueled arrangements.

It is very easy to do by the government to block the bitcoin wallet and its trade. Maybe if a country indicates a big problem with bitcoin use and the amount of money laundering in that country with bitcoin mode .. maybe that could happen. Criminality caused by bitcoin transactions to the detriment of a country. It will cause the state will not allow bitcoin to flourish in that country.

Not really doable.

cryptocurrencies are designed to counter this sort of government intervention in transactions. There is no central point of failure, for a country's government to say no to bitcoin completely they would have to shut down every single node that runs bitcoin which is impossible. This is in stark contrast with centralized payment processors such as LibertyReserve and e-gold which all got taken down very easily.

Your idea about ISP blocking online payments will firstly spark public outrage and secondly, probably wouldn't work very effectively as workarounds can be implemented quite easily. And plus, how are they going to block bitcoin transactions in the first place? I'm not aware of any obvious ways of doing that.

Any country that attempts to do that has to be kidding. Bitcoin is anonymous for christ’s sake so how would you plan on blocking it when you don’t even know who is carrying out the transactions.

In what matters or problem why would the government is blocking bitcoin in your area? As far as i know the government doesn't care about much for bitcoin as long as it is not causing any trouble for any certain areas.

For the record if the government will ever going to do that i think there is already a chaos happening because if they did block it like what you said 'block the IPs/ISPs' there's a serious business going on that matters about the crypto currencies world.

I think you were just thinking too much or beyond because first and foremost why would they have to block it anyway? People can always find a way to access the internet even if you have to block their ISPs or IP addresses, so it doesn't make sense at all.

it is not as anonymous as you may think although it can not be completely blocked. but causing a lot of troubles is easy, just announce it illegal and people will simply stop using it!

Maybe they do not have a direct way to block bitcoin, but if they find a way to differentiate between normal traffic and bitcoin traffic they could try to block it, or they may try to block websites that talk about bitcoin like this forum and exchanges.
