You are not taxed on capital gains. You can be taxed on your “sostanza” but only once it is over 300,000! Of course there are many deductions including your mortgage if you have one so it’s not so easy to get to that level.

At that point it is 1% of every Franc over that amount.

Tax on the mining aspect is another thing since it is considered as earned income.

I will be speaking with my accountant more about this but in the meantime @steemitri posted a link to the circular put out by Canton Ticino in comments here.
