What if the governments across the world attempted to seize all of your crypto assets like the US seized all gold from their citizens in the 1900s. Now I'm seeing articles talking about how the US government is trying to be able claim private property.
I think that ultimately this would be very challenging for any government to successfully accomplish. This would cause a revolutionary period again in our world I imagine....
If it is something so easy for government to put a stop or seize cryptocurrency they would have done it longtime ago. The highest the government can do is to regulate how cryptocurrency can be used, and if this should be done it won't take much effect to crypto users, their would still be away people will still make use of cryptocurrency. Since cryptocurrency is not controlled by the government it is impossible for crypto assets to be seized.
I have another question, what do they confiscate cryptocurrencies for? Cryptocurrencies are not yet comparable to gold, gold is much more valuable, so comparing crypto to gold in this case is a bit lame. The entire crypto market cap is only one-tenth that of gold, and its growth is being held back by the government by simple lawsuits. So the hypothesis that the government will confiscate the cryptocurrency is not viable and can never happen.
