Responsible for editorial content
Responsible for editorial content pursuant to section 18 (2) of the German Interstate Media Treaty (Medienstaatsvertrag, MStV): Stefan Dzwonek, NexTao GmbH, Königsallee 27, 40212 Düsseldorf. Every text in this magazine is checked by the editorial team before publication, and the team answers for it. How we work is set out under About us and the editorial team.
No investment, tax or legal advice
All articles, tools, prices and figures in this magazine serve general information and education. They are not investment advice, not tax advice, not legal advice and not an invitation to buy or sell crypto-assets. Crypto-assets swing widely in price, and a complete loss of the money invested is possible. For decisions with financial weight, turn to an authorised adviser, and in tax matters to a tax adviser.
Prices and chain data
Prices come from a large European trading venue and are taken over roughly every ten minutes. Chain data such as block height, difficulty and fees comes from a public Bitcoin node. All values are delayed, can differ from those at other trading venues and are shown without warranty.
Interactive tools
The tools in this magazine calculate example values from the figures you enter, and explain how they get there. They work with simplified models and assumptions, which are named on the page in question. The graphics the tools produce are created in your browser from your own entries; what you do with them is your decision.
Images
The illustrative images in this magazine were created with the help of artificial intelligence and show no real people, places or products. They are marked on the pages as AI illustrations. No image is loaded from an outside server.
Dispute resolution
We are neither obliged nor willing to participate in dispute resolution proceedings.
Liability for content
As a service provider we are responsible for our own content on these pages under the general laws. We are not obliged to monitor third-party information that is transmitted or stored, or to investigate circumstances that point to unlawful activity. Obligations to remove or block the use of information under the general laws remain unaffected. Liability in this respect is, however, only possible from the point at which a concrete infringement becomes known. Once we learn of such infringements, we remove the content in question without delay.
Liability for links
Our offering contains links to external websites of third parties, over whose content we have no influence. For that reason we cannot accept any warranty for this outside content. The respective provider or operator of the linked pages is always responsible for their content. The linked pages were checked for possible legal infringements at the time of linking, and unlawful content was not apparent at that time. Permanent monitoring of the content of linked pages is not reasonable without concrete indications of an infringement. Once we learn of infringements, we remove such links without delay.

Reproduction, editing, distribution and any kind of use outside the limits of copyright require written consent. Downloads and copies of this page are permitted for private, non-commercial use only.
