Portugal remove capital gain tax if you don't sell in the first year. Might not be great to spend and replace, but you can use a small non-kyc wallet for this and don't touch your large holding for tax purpose. Also I hear it might change, not sure when and how.

Switzerland has no capital gain tax at all but wealth tax. Starting around 100k of wealth you will be taxed about 0.1% per year, then it increase up to 1 or 2% depending on the region you live in. Not bad but not great either.

There might be other options, DYOR. Just avoid Italy...
