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!
I hope you have understood what is a bitcoin address and what it is used for by above replies.
Just want to tell you that if you want to create a bitcoin wallet address with ease, search xapo on playstore or visit xapo.com directly from your browser.
Create an account and copy your very own btc address, paste it in bctk profile of wherever you want to give it.
All incoming btc gets stored into your xapo wallet.
