I know many governments are blatantly corrupt and don't care about the people. But using bitcoin to evade taxes is also not a good idea. If we do that, we are using bitcoin against the law, and that is a bad reputation for bitcoin. Moreover, it is not true to say the government does not help us, your job and your safety... are taken care of by the government. They play an extremely important role in creating the society in which we live and exist. We can't completely deny their role, but they are really too greedy.

Well I get your point and I don't know if you're from my country or you ever lived in here and please don't get me wrong by thinking I'm trying to paint my country red but the truth remains that the government of my country doesn't have any direct positive impact on its citizens because I see no reason a civil  servant will serve a country for over 10 years and above and  battle  with pension and gratuity and have no empathy for its citizens.

My country is a messed up country and there is no way I should be singing praises of it when it is already messing up.

In a democracy this can't really happen. If any political party would consider taking away large sums of private money, there would be a huge public outcry and the politicians wouldn't be in power for long. Who would vote for a party that wants to steal your money? And even if the presidents finds a legal loophole to push it through, there would just come to opposition and bring it all back. You can't have policies that affect the majority of a country negatively. In a communist or dictatorship country this might be different, the politicians in power can choose freely and don't worry about what the average person thinks. But even in such a situation the question remains, how will the government manage to get access to all the private wallets. Just by demanding the people to give up their crypto coins, doesn't mean that everybody will so. I would expect for most people to not give up their coins and instead hide them from the government.

Governments won't be able to take crypto assets from every citizen, in my opinion. Governments' sole option is to outright outlaw cryptocurrency in their nations, but even that will make it more difficult for them to seize cryptocurrency holdings from any individual citizen. I don't believe there is any other way for governments to seize a large number of people's crypto assets without their surrender. The only way I can think of is through exchanges, such as when exchanges have a problem with them and decide to shut down completely, which will not be simple to do.but Once your coins are in non-custodial wallets, I don't think there is no way for any government to seize your coins.

If it is possible for government to seize crypto assets like physical properties, many governments should have try that because many of them are enemies of crypto and they don't want its existence again because they know they cannot do anything to control it.

It is possible to hide the Bitcoin assets that we have from the government, but at this time the government has also used people who are smart in tracking Bitcoin assets where these people certainly understand how Bitcoin is and also the wallet used to store Bitcoin. I also really appreciate your opinion on this matter because it is a fact that is real and can be found in the current environment.

So that in addition to the benefits that can be felt by Bitcoin users in terms of keeping Bitcoin in secret, Bitcoin users will also get greater benefits if they live in a country that has legalized Bitcoin and have never questioned Bitcoin users for anything. I imagine it would be very happy if in the country we live in, all shops and restaurants would accept Bitcoin as payment.

This sounds strange to me, how can we pay taxes while our investment is losing? As far as I know, the government will only tax those who generate income from cryptocurrencies, and I have not heard that long-term holdings will also be taxed every month. If that's true, then that's the ridiculous thing the government is doing. I will never pay taxes, even if I make a profit on my investment.
