An apology if I'm uneducated. I am a new enthusiast of this cryptocurrency and recently downloaded your wallet on android, my question is as follows. I generate a new clear wallet. However, the first time I clicked the receive button, I found an address that I gave as an immobile, however I realized after about two transactions that this address changed and I was wondering why? If you were supposed to create a wallet and take it for granted, you would have a unique address. Is this a problem or is it normal? if it is affirmative, I ask for your heart, please instruct me. I apologize for the length of the message is that I do not know where to ask for advice. also because of my bad english google helped me. By the way do I have a private key with a few coins where they recommend me talking about security to be able to import it? otherwise I can import my key from the android wallet to the pc only with the phrases? Take me out of this dilemma.
