Help with BTC pleasr

[Hostage]

So I have downloaded bitcoin wallet on my samsung mobile.

When I open it it tells me my bitcoin code.

If I sell something and I receive bitcoin, do I redeem it in my wallet?

After I have the amount, can I transfer it from btc to my bank?

Please help me I want to get into this as paypal is wank.

Thanks and mature answers only please.

First of all what Bitcoin wallet have you downloaded?

And it should be your Bitcoin address that you receive money and send money with, if you're in the US link your bank account on coinbase.com and just convert it through there.
