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

I can earn 1 bitcoin in 2 months. It's quite fast for me, lol. There is no fast way to earn bitcoins, the only fast way is gambling and it's very risky.
Also there is no shortcut in earnings, it will really need takes time. But if you really like to earn bitcoin fast try to find your luck in gambling but as they said its too risky. and instead of achieving it earning big you will never notice you will lost big in gambling.
