The interface looks elegant and easy to use. I tried the service without registering, but I was surprised on the next page that you were requesting email or Telegram. Why?
I mean, is it possible to use the service without registering? If the answer is yes, why should email or Telegram be registered? If this is a P2P exchange service, there should be privacy for users who do not wish to register and reveal their identity, and therefore it is not necessary to register email or Telegram.
Registration is not required. Mail or telegram is requested to record the exchange history in case you need help. The identification of the request is based on the data that you specified when creating the request. You can write anything in the login field, but try not to make mistakes.
