hello and welcome to the forum.
 by now almost everyone has answered your questions.
but would it be better to understand what you actually signed up for on this forum, to learn or to earn?
I advise you to be active and participate in the discussions on the forum, the time to earn btc should be left out for the moment, if I were you I would focus more on learning what btc is and everything that revolves around it and then when you have gained enough trust and merit you can think about how to earn btc
