Trading is the one way I really feel that can help you in earning that amount in limited time frame and many people will prefer even gambling to win it quick but majority of times they will be sitting on loosing end and will loose all the capital that they have.
Trading is most favorite way to using the bitcoin and also earn bitcoin. Trading is a profitable way, but don't forget, it is hard to earn 1 bitcoin within 1 or 2 months. Only one way is here to use the big capital to earn 1 bitcoin in a month, than it is possible to earn it, instead we are doing trading or investment.
Yes to make profits of 1 btc from trading will also require good capital to invest at initial stage as you will never make such an huge profits by investing smaller amount as smaller capital will give only smaller profits for you and higher investment will encourage higher risks too.
