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.
I think your title and post are somewhat disconnected. I think you in particular might be more interested in blockchain technology just based on how you talk about bitcoin and emerging technologies. With bitcoin and the idea of "getting rich quick," I would change your title to be: "Bitcoin takes money to make money." To make decent amounts without being too risky, you would need to put a
lot of money into ideal coins at the right times. The buying low/selling high concept is pretty easy to keep up with, but the hard part is getting the seed money that you can actually afford to maybe lose. In that lies the true challenge of making money off of BTC.
