I think y'all maybe missed the point of the link I posted today, this isn't old news from 6 days ago. The link explains that purchases with crypto are VAT free. This follows from a clarification by the Portuguese gov't a couple days ago. Note the quote below isn't talking about investment gains.
According to a report published on Aug. 26 by Portuguese business newspaper Jornal de Negócios, the Portuguese Tax and Customs Authority have confirmed that crypto transactions or payments are exempt from Value Added Tax (VAT).
Not your quote, but this quote is talking about it, as far as I understand :
Portugals Tax Authority has clarified that both cryptocurrency trading and payments in crypto will not be taxed in the country, Cointelegraph en Español reported on Aug. 27.

The agency reportedly provided the clarification to a local crypto mining company, publishing an official ruling document. In the document, the authority states that the exchange of crypto for fiat money is free of VAT, adding that crypto users do not have to pay any income tax.
