I am a newbie here. Can somebody tell me what is "bitcoin adress"? Because i saw that i need to write it in my profile, but i don't know what is that, or where can i find it. Thanks a lot for help!
Bitcoin adress is your wallet address that is used to store bitcoins.You can download wallet from app store for free there are many good wallets.I would suggest you to use Blockchain or Mycelium.
