If I am mistaken, the first country in the EU to pass such a law was Germany, where that period is 1 year, in Croatia it is twice as long and amounts to 2 years - while there was a lot of talk about how Portugal and Slovenia are very friendly when it comes to laws on taxation of cryptocurrencies, but I am not sure if that is still the case.

Yes 1 year in Germany but this law doesn't revere directly to bitcoin. This is called a "privates Veräußerungsgeschäft" (private sale transaction) and applies also for gold and other stuff.
