You are not the one who is confused, we are also confused with your question. You have asked that "how will you earn bitcoin for a week or month" and you said that you have bitcoin but you just don't know how and where to spend it. I think you are trying to ask "How do you earn bitcoin in a week or in a month" and not "how will you earn bitcoin for a week or month" because you do have a bitcoin and you are asking "how will you earn bitcoin for a week or month", it is really confusing. Well, to answer your questions. We do earn bitcoin weekly or monthly by signature campaign or some Altcoin campaign, you know the Bounty stuff mostly because it is the easiest thing to do than doing signature campaign in the Altcoins Campaign.

1. how bitcoin help our daily life
2. How we earn bitcoin in weekly or monthly basis / probably he asked how we can grow our bitcoin
3. How we can spend your bitcoin / where to spend bitcoin since he have bitcoin but does not know what to do with it.
