I'm from Croatia & here, as I know, the laws are a bit lighter.
But, there's an example of paying off to yourself the so-called "capital gain" of the crypto currency trade on the online exchange markets, the government, by the law, has the right to take 45 % taxes. It is crazy! & it is your obligation, when you pay off to yourself in the local money "kuna" directly to the bank account, to report the transaction & to pay this taxes.
Anyway, If you never change any of the crypto currencies in the any form of the any state's official money directly on the bank account, the government cannot follow the money flow & the can't never ever demand the paying of taxes cause there is no proof for them that the transaction ever happened.
For example: If you have 1 000 Steem $ & buy a camera online with the Steem $, they cannot trace the transaction & are not able to take the taxes!
Weeeeeeeeeeeeeee :)
