Says its considered a currency, so if you exchange it, there is no added taxes. If you have a income in BTC, i doubt it doesn't count as income, especially if you convert it to Euro at any point.

This just means that its not like in Brazil where they pay like 20% tax when BTC get exchanged to US or Reias or anything.

So i would not consider it tax free, unless the country you live decide to also exempt BTC income as taxable income.
