Glad you came by. Thanks for your edits, I made necessary changes in introduction as well as point (1) i.e. the definition of Public Address. Please check and tell me if anything else needed correction. .
Yep, now everything is pretty good. I remember that i had some more remarks about your text, and i will try too look into it a bit later, but for now i'm a little busy. But yeah, intro is now looking good.
Ok! So let's start with the topic. To use Bitcoin, user generally needs two things: Private Key and Bitcoin Address. Bitcoin Address is an identifier which looks like this: 18J6ai34uzGofUuzbiwhXJzKzdx1efDBqA. User have to share it with sender to receive payment. Whereas private key is a key which user have to input in wallet to access the funds received.
