Am new here, pls educate me,

I call Jerry from Cotonou, Republic of Benin. I recently downloaded the Bitcoin kernel on my Android phone by following the video clips of a man named Chris Dunn. I've watched all its basic educational clips from the 1-5 base version, but I still have problems using it for transactions. Pls what can I do, how will I use Bitcoin for daily transactions, how will I put money on my Bitcoin account in my country, or how will I exploit Bitcoin. Thank you
