You should never expect to get rich through bitcoin or any emerging technology. It is always important to be alert to anything that sounds too good to be true, or is against the fundamentals of economic law.
Bitcoin is a growing area of innovation, and there are opportunities and risks. Even so far, bitcoin has been growing at breakneck speed, but no one can guarantee that it will continue to grow. Any investment in bitcoin's time and resources requires entrepreneurship. There are many ways to make money from bitcoin, such as mining, speculation or new business. All of these methods are competitive and there is no guarantee of profit. Each person should make an appropriate assessment of the costs and risks involved in any such project.
Those are really general facts about the bitcoin besides the thing that we dont know how far it will go. I know its risky one considering the timeline for its development and the speed that it has currently. But, with some countries help like Japan, European's and some part of the Asia I do believe that bitcoin technology could get pushed further. In reality though rest of the world denies the acceptance of the bitcoin then also two to three countries are sufficient to run the bitcoin business and keep it alive. They could actually become the pioneer in the field and other countries might beg for the advance technology from them. Lolz. Anyway, making money with BTC is different aspect of it and its there today and may not be there tomorrow who knows!
