Bitcoin is known as to be the biggest cryptocurrency. in some countries it can be used to purchase goods and services and some see cryptocurrency as a threat.
if Bitcoin comes to be number one currency in the world today, can it be hijack by the government?
I don't think that someone can just take and steal Bitcoin, especially when the keys to your wallet are only with you. However, depending on what is meant by the word "steal". You can, for example, lure you out, force you to sell your BTC, and then anyone who wants to become a manopist will be able to redeem all BTC. As for the governments, I don't think they are interested in BTC at all, in terms of taking possession of it. BTC is currently out of the system and this prevents it from being used all over the world. But the system itself is now on the edge, which means you just need to wait and see what happens.
