Dear user,  as we mentioned before,  the app has testing amounts of ebits on it,  we will post a guide once the app is past the tests.  Receive button is disabled for the time being.  It will be usable once the app passes the closed tests.  In the close future as of now it will be ether,  then ofc bitcoin,  after that most commonly used currency such as dollar's ,  euro and funt. Later we will expand it more but everything will come with time
