Google translate is translating your article to "VAT" (value added tax).
But I'm asking about tax on bitcoin profits (I hope it is self explanatory in every country that there is no VAT on any bitcoin trade)
That is correct, it was only the VAT part that was dropped. You still have to pay capital gains tax for profits, but losses can be deducted. Depending on how much time you spend trading they could also decide that the profits should be taxed as income from work, which has a higher rate. It's not possible to know in advance what it will be.
