Hey Meira, thanks so much for your feedback! I think you're right about the email sign up, it's purely for the private beta roll out and we use three-way encryption to protect users who sign up. We plan to allow Bitcoin, Dogecoin and Litecoin :-) German laws oblige us to ask for paying users data (e.g. name and address) but we don't actually check or verify this data. Free users can sign up and provide zero information (apart from an email during private beta).
