You cannot simply eliminate a technology that are decentralized. If Bitcoin was run on centralized servers, some government could have taken them down, but not Bitcoin. Bitcoin runs on 1000's of computers and cannot be taken down at the same time, these computers are spread globally.
The governments may implement strong laws or regulations, but people will still be able to use it globally. ^smile^
Trust me, if government really wanted to destroy bitcoin they would do it already. It may not be easy but it is doable.
1. If they would initiate a BTC ban and heavy smearing campaign, it would put off majority of people from using BTC.
2. They can't kill the network, but they can hinder it greatly. For example, gov can target ASICs manufacturers. Disrupt their business or try to force them to add a kill-switch to their products etc.
1. I would like to ask; When we speak about the government. Which one? The Chinese, the USA, the Russian or anyone elese, because till now there is not a universal government. On the other side there countries like as
Switzerland which is crypto currency friendly.
2. No they cannot because they know that after every ban or a hostile movement bitcoin always is getting stronger. Only bitcoin will kill bitcoin and the governments as well as the banks know that. If bitcoin ecosystem will not find a solution in scaling issue then people will not use bitcoin as payment system but only as commodity in exchanges and markets. So fiat will have not any fear from this usage of bitcoin.
