we want to know how fast you earn 1 bitcoin? so that a newbie like me can learn more about bitcoin and gives us encouragement to pursue bitcoin

First of all. Welcome to Bitcoin.
As much as i like to break the goodnews, there is no such thing as earning fast. Everyone must be familiar on things that they would want to know. So i encourage u to read all the pinned threads. Visit all the threads in our community.
Most bitcoiners probably would start with fauceting. It is where you can get microcoins by just visiting sites. And the most common is joining signature campaign.

Bitcoin does not come magically into your wallet it is a currency that you must work for before you get it
I will advice you to do local jobs and buy bitcoin with your payment then lean trading atcoin don't gamble except you are full with luck (very risky)
That was how i started earning bitcoin and at-lest it has helped me alort
