No taxes in my country, on buying/selling crypto if you are doing that as an individual and not as a service to/for others. In this case and in case of mining you are obliged to pay taxes. But I believe that as in most of EU countries the regulations will become more clear in next months and upcoming years. What is interesting is that some of the political parties are already having on the agenda "crypto free of taxes" what is a nice add on to the usual agenda.
