The diploma thesis describes the advantages and risks of cryptocurrency trading. Some present cryptocurrencies as something positive, as a new business opportunity, others as something negative that opens up new opportunities for money laundering, tax evasion and crime, as an opportunity to make a profit, and as a threat to speculative predictions of a sudden drop in cryptocurrencies. Thus, there are many cases when investors became rich overnight with the help of cryptocurrencies, as well as cases when they suddenly became heavily indebted and bankrupt when the value of cryptocurrencies suddenly fell. The amounts we are talking about in the case of cryptocurrencies are by no means negligible. The reason for writing the work is to show how well we know cryptocurrencies in Slovenia, how we use them or even trust them in such a way of doing business, which advantages and disadvantages of cryptocurrencies we could see, and ultimately the adoption of cryptocurrencies as a new payment method. Descriptive and survey research methodology were used. The results were also processed with statistical tools. The result showed that respondeds agree that in the future cryptocurrencies could replace traditional financial operations. Respondents are also noticing the effect regulations have on dealing with cryptocurrencies, but they don't see regulation as a bad thing. Quite opposite, as they see its of potential with reducing levels of financial crimes and corruption. Respondends also think that digital way of dealing with finances gives them anonimity and security. They believe that in the future cryptocurrencies could replace traditional currencies that we know today. They see them also as viable investing option. They value the anonimity, security and usefulness of cryptocurrencies, beause all three categories got good results in the survey. The respondends also don't view cryptocurrencies as risky.
