I already give all of my transactions and trades and movements to my government, with my information, and pay my taxes on that. I am not sure why that would be a bad thing at all.
I understand why people wouldn't want to pay taxes to their government, but without you paying your government, then the world would be in chaos and it would be naive to think that they use all of your tax money on you, of course they steal, they are politicians, that's their job but they also spend some on keeping the nation going, so even though we hate our governments, we still have to pay our taxes to keep the nation going, and if we don't and they bankrupt because of it, we will be the ones that bankrupting because of it, that's not a good alternative.
That is the right thing to do, and that is how the world turns. There will always be some people who will think individually, they will think "I shouldn't pay taxes and find loopholes to avoid it" even when they know that government has to sustain to keep them alive as well, they just think others would pay their fair share of taxes, or they just think there are other people who do not pay full of their taxes so why they should and these type of thinking causes a lot of people to try to avoid their crypto taxes as well.
If you traded and if you made some profit then you should pay the taxes of that if the country wants it, if they still figured that out then you are lucky but if they come asking for it then you should be paying.
Talking about taxes is always ambiguous and can lead to many disputes. Each person has his or her own point of view on this issue. But I have realized one thing over the years: it is better to pay taxes and sleep well! When there is a law in my country that will allow me to pay taxes on cryptocurrency profits I will simply pay them and not worry about my property being seized.
