According to CoinMeta, Greece has just established a tax rate of 10% on crypto earnings (with the first 500 euros per year exempt from taxation, starting in 2027), making it one of the lowest tax rates in Europe. Denmark has the highest tax rate, at 52.1%, while Germany and Portugal impose a 0% tax on cryptocurrencies held for more than one year. In Europe, the length of time one holds a cryptocurrency may be more important than their place of residence.
