That said, i no learn everything at once oh, e get when i be newbie and i no know much about bitcoin, but i dey read wetin knowledgeable users been dey post, na so i begin dey garner knowledge, until i became good at a lot of things concerning bitcoin. So anything wey you wan learn about crypto, na here you go learn am.
