Anyone who sells their coins and cannot prove the purchase price will in future have to pay tax on half the sale proceeds. This substitute assessment appears in the German Federal Ministry of Finance’s draft bill on the “Act to reform the taxation of certain crypto assets held as private assets”, and it is the point that has so far been lost in the debate about the one-year holding period.
