They can try, but they wont succeed. The whole concept of decentralization is what will protect Bitcoin and other cryptocurrencies from governments. They are trying to delay the inevitable!!! Change is coming, they will lose their grip on the world and we will all have equal chances to succeed... 

i think the government cannot destroy bitcoin.
bitcoin is an advance technology, it is decentralized. But the regulations about bitcoin may affect the price of bitcoin.

the government will never break bitcoin because its users and investors can only damage because they control the price.

on the scale of the country concerned, they may be able to minimize the bitcoin space. but it will not just close the chances of using bitcoin in the country. technology continues to grow, they can not shut the internet completely. many avenues can be done to keep doing bitcoin transactions, such as the use of VPNs, proxies, asset sales in overseas markets. it sounds illegal and criminal, but that's the reality that the movement of bitcoin will not be dammed.

The ban does not destroy bitcoin. It seems to me that bitcoin can be destroyed by legalization. It seems ridiculous. But I can explain everything. People are attracted by decentralization and deregulation of cryptocurrency. Many people are now faced with the problems on the exchanges because of the regulation. Do you think this will add to the popularity of bitcoin?

The simple reason that they won't succeed is that bitcoin is a centralized coin. So with the availability of internet service, a hodler can still have an access despite the restrictions.

Destroy, no.   Cripple, yes.   

I can even say how they can destroy! they can just buy up the bulk of the coins and that's it. The market is dead)

I think hard on governments around the world, what is the reason the government forbids Bitcoin?
If I think Bitcoin does not harm all countries so why Bitcoin should be banned, the question is why the new government recently forbade bitcoin to grow, that we know that bitcoin has been going on for quite a while, even where the government at a time when bitcoin prices are still cheap, and there is no ban from the government, whether the government is urged by the banks around the world, so bitcoin growth is not too widespread, of course not, even more and more new users to join Bitcoin ...

i don't think that government can destroy Bitcoin , if they can do it why they let Bitcoin enter to wallstreet ?
