That is not the problem. It's obvious that if you are getting paid in bitcoins in here, the government isn't going to know unless you report it, I don't see them bothering asking theymos for IP records or something, and most people use proxies anyway, for safety reasons in here, since using your real IP in here isn't very bright due all the scammers trying to dox each other.
The real problem is, how the hell do you properly cash out your bitcoins if you want to buy a house with them? because there's no way you are going to avoid the government knowing if you want to buy a house with your signature campaign gains across the years. So far none has given a real answer to this.
Most governments won't be monitoring crypto transactions extensively right now, but it's only a matter of time before they do. Do you think they're just going to sit back and let people earn millions in crypto without paying the taxes on it? The US has already sent legal requests for Coinbase to give up the details of people's accounts there. They could just as easily send theymos a request to do the same which he would have to oblige if it was court ordered. These things have a way of catching up with you. Like I've said before, you might be able to get away with paying no taxes for a while but if you start to live beyond your means it starts to look suspicious. You might be able to earn a decent living here but when you want to buy a car or house big transactions get reported and to buy a house in my country you have to prove where every penny of your money came from on any sort of deposit. There's no way I would be able to buy anything of substantial value without it coming back to bite me eventually. To answer your question, you just declare income earned. This is what you're going to have to do if you want to buy a house in the future.
My government did not legalize bitcoin yet so I can use bitcoin without pay any tax.
Usually I earn btc and convert into local exchange , I just paid some fee from transaction so I do not pay any tax.
Other exchange may apply tax because they already legalize bitcoin
Just because something hasn't been made legal yet doesn't mean you don't have to pay taxes on it. Seriously, contact your local IRS and ask them if you don't have to pay taxes because your earnings are in crypto. If an employer decided to pay you in gift certificates or credit vouchers or some other form of token that they had created do you think that would exempt you or them from taxes? This isn't how it works. If it was people would just start creating their own money or pay people in goods etc to avoid taxes.

1. I don't consider not sharing information about my private possession with anyone as wrong.
It doesn't matter what you consider. I'm sure you share lots of information. Do you not have an actual job? Do you not pay your taxes there? Do you have a debit/credit card or any other bills? Are you completely anonymous and live self-sufficiently off the grid? Or is bitcoin just a way you can finally get away with quietly sticking it to the man because it's a payment system outside of the mainstream where you think you're safe?
2. Here in Europe, in most countries you are supposed to pay taxes from realized gains, so until you spend your coins you don't have to pay or report anything.
Europe is a continent and nobody pays income taxes to it. I can tell you in most countries I know of it's actually the opposite. Each specific country has their own laws regarding taxes and your logic certainly isn't right regarding Spain or the UK.
By law you're supposed to pay when you make purchase or exchange for fiat, so I haven't reported anything. Even if this law changes at some point, I still won't do it.
What country are you in? This isn't usually true in the vast majority of countries.
3. There's no need to launder the money. If I ever want to get fiat (don't think I will anytime soon), I'll do it on a German exchange, where we don't have to pay any taxes, at least for now.
That depends on whether you're a citizen of Germany or not. Germany might not require capital gains tax on bitcoins (yet) but I'm pretty sure they still require you to pay income tax on them as earned.
http://www.nomoretax.eu/bitcoin-tax-haven-germany/Was your ethics so influenced by the system that you feel the need to report your every move to the authorities?
No. Why would I report my every move? This isn't a debate about reporting movement. It's about required income taxes and the law of the country you may or may not reside in.
That you feel like you're doing something wrong when you don't tell them what you spent your money on?
You don't have to tell them what you spent your money on. This is about income earned and tax laws.
Soon the society will become so scared that there will be no need for surveillance and tracking. The good citizens will share all information of their free will and even feel good afterwards.
Again, this is about income tax laws not anything else. I think a place where lawlessness exists because there's no roads, police or doctors because everybody just evaded or stopped paying their taxes would be much worse than this hypothetical self-reporting surveillance state. Personally I don't think it's fair that some people think they're above the law and are happy for others to pay their way whilst you take all the benefits the country provides you, just on somebody elses tax dollar. There are plenty of countries you could move to though if you don't want to pay income taxes. They tend to lack it other benefits, though.
