To optimize your trading experience on Cryptohopper, we have added many features that you can enable or disable to your liking. The first things you can fill in are your personal details. These details are needed for multiple reasons. For example, it is impossible to buy a subscription without filling in the necessary text fields shown with an asterisk *. Additionally, you can apply to become a Marketplace seller when you share your details. Another reason is to make sure Cryptohopper fully complies with European taxation laws.
