In order to be able to purchase cryptocurrencies securely as an investor, you need regulated companies that offer cryptocurrency trading. In order to be able to offer this, you need either a permit to operate the financial commission business or to conduct proprietary trading. In the financial commission transaction, a party acquires cryptocurrencies for the customer on behalf of the customer in its own name but on behalf of the customer. In self-trading, the party itself trades the cryptocurrencies on its own trading book and serves as a counterparty for buy and sell orders — usually for financial commissioners.
Below, FinPlanet provides an overview of regulated companies that have appropriate licenses in Germany and also actively offer the business for cryptocurrencies.
