I'm from germany and would like to know how private bitcoin profits are taxed in spain .
Just the profits from normal trading on exchanges and holding coins not longer then one year.
In germany it is a "private sale" and the profits are added to your income, except you holded the coins one year or more.
How is it in spain ?
In Spain the profits for selling bitcoins which you have kept for less than one year are added to your income and taxed as such. All those profits would go to the "base general".
You can find the rates that apply here:

EDIT: There may be some differences in the table of the "base general" depending on your "comunidad autónoma". The table above for the "base general" applies to most of Spain, including Madrid. However, Barcelona may be approximately 2% more expensive.
If you keep them for more than one year, the table that applies is called "base del ahorro". For more than one year:

I am not an expert in finance but I think it works that way.
I think Shawshank is right but not in the last point, as pharesim has said. It used to be like that but government changed it in 2015. So, it doesnt matter how long you hold them.
Something that hasnt been said is that as far as taxes are concerned, a miner is considered a businessman, so tax to pay is different: it is the IAE.
