This is straight forward, there is nothing against bitcoin and crypto here, they are applying the same rules that already exist for other trading. What, you thought you could trade with non-cash goods and that wouldnt have been exploited for decades? Have shares and trade for gold, or vice versa, no taxes to pay?
Of course not. Your country wants you to declare your earnings, income, profits, and pay tax on them regardless how you made them.
But that is now, do you think they are going to be so open with bitcoin when in the future bitcoin begins to be used by a huge number of people in their countries, they will realize at that point that things are getting out of hand this is why we see the media bashing bitcoin as well, that way if politicians need to ban bitcoin in the future they will have created a lot of ill feelings against bitcoin already.
