In Germany, crypto-currencies are not legal tender, they are classified as private money by the Federal Ministry of Finance (BMF). They are thus similar to external effects, which is why no value-added tax is payable on exchange and trade. In general, speculation and the associated sale of crypto-currencies is basically a private sale transaction. Whether one has to pay taxes for this business depends on whether a capital gain has been made and whether this has taken a long time.

If you buy crypto currencies such as Bitcoin today and hold them for more than a year without selling them on the stock exchange, for example, the coins can be sold afterwards and any profits are tax-free.
Every realization of profits is a tax-relevant event and must be properly recorded in advance.

For crypto-currencies there is a tax-free limit of 600€, this limit is dropped if it is exceeded. Therefore, one speaks of a tax-free limit and not of a tax-free amount. This exemption limit includes not only crypto-currency gains but also all similar gains from similar private sales transactions.

Our recommendation is to hold coins for at least one year and only then to sell them, that daily trading should be avoided, because you have to pay taxes for every transfer and possible profits. Even if your profits are below the exemption limit, you must declare this realisation in your tax return, as the tax office will determine whether you are exempt from tax.
