As we are neighbours, this exemption is well known here in Spain, and some Spanish bitcoiners have already temporarily emigrated to the Portuguese country.
Interesting! I had no idea about this situation.
But have you been buying a house in Portugal or are you just renting?
Neither one nor the other: I'm living in Spain and have no plans to emigrate long-term, but among those who know Bitcoin relatively well in Spain it is known that, if you stay more than 6 months in Portugal, you pay your taxes there, and since gains from cryptos are not a taxable event there, you can withdraw/exchange for fiat for free.
I remember a couple of TV programmes explaining the situation, with interviews to not only Spaniards but people from other countries too, who were living for a few months and/or buying houses. There was even an agency with travel plans etc. so they managed everything and holders simply enjoyed their vacations.
