Select what genuinely interests you. Your picks feed directly into our editorial planning. If you hold bitcoin on two exchanges and in a wallet of your own, and then sell part of it, you need to know which of your tranches counts as sold. That is what decides whether the sale stays tax-free. The answer goes by the name of crypto FIFO, and in Germany it works differently from what most holders expect: the Federal Ministry of Finance does not calculate across your total holdings but separately for each wallet and each exchange account. A sale on account A never reaches the older coins in wallet B, however long they have been sitting there.
