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.
Yeah, Gambling is the best ! I almost multiplied my Bitcoin in just a month. My 10M satoshi became 20M Satoshi in just a month. So thats one of the best way to earn money. Just look for the best gambling sites that you can and look for its strategy. I suggest Betcoin.ag.
That will not be the case with everyone in gambling, just some particular lucky people manage to win in gambling and others always has to taste the loss of money and that is not a good thing if someone is not willing to lose anything.
