The growth of cryptocurrency presents a threat to the traditional finance system. Blockchain technology can be implemented more efficiently than it is with implementing a traditional financing system. Cryptocurrency is based on Blockchain technology or similar ones to it. Cryptocurrency is now adopted in the fields of food, drinks, online buying but is also responsible for developing new work fields and creating new workplaces. When they were first created, society was not introduced or educated about this type of currency. Even though there are all sorts of data about cryptocurrencies, people are still skeptical about them and their use. This is why many scientists have taken a closer look at this particular financial field. Fiat money or real money (paper money, credit and debit cards) is more secure because a person has ''full'' control over it but because there are third parties involved, people are leaning towards cryptocurrency because of its efficiency and smaller costs. Even though cryptocurrency has many advantages there are also disadvantages to this type of currency such as fact that there is no central point that controls its development. This is why before cryptocurrencies are fully implemented in everyday life, there is a need for creating and bringing rules and laws that help fulfill these facts.
