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.
That is why bitcoin became famous, bitcoin is outside the fundamentals of economic law, where there are less opportunity for people who are just normal part of the society. Only rich people become richer, in crypto even a normie can earn a lot because of technology innovation, crypto currency, block chain technology and more. What is wrong with people who are into crypto and block chain is expecting to become rich over night. Take note that people who became rich in it are those who patiently waited for crypto to become really well-know and for the price to spike.
