To what tax are you referring to? Property tax or realized gain? 24% is nowhere close to little.
The total. Here, the income tax is around 37-56%, and the "property tax" is around 2% each year.Quote

There are much better options, like the one in Germany where you have no tax if you can prove you held your coins for more than a year.
Or you can go to Poland, they have 17% income tax up to 25 000 EUR and 32% on whatever you earn above that.
56% income tax is probably one of the highest income tax rates in Europe. Usually found only in the cold North like Finland and Denmark. Their tax rates and food prices can make you consider suicide.
