Cryptocurrencies are around for less than a decade but their usage steadily increases. There is no doubt that functional, social (cool-factor) and financial (high risk -high reward investment) motives drive its adoption and usage. But it is also worth to investigate whether personality and demographics can play some role in the adoption. The research have focused on impact of personality traits (according to the Big Five Inventory framework) on the usage of cryptocurrencies. The research was conducted in the Czech Republic. Respondents were university students, 478 in total (272 male, 206 female; 20.5 years old on average), of whom 62 respondents indicated that they use cryptocurrencies. Gender, age, and type of student job were used as control variables. With regards to the results, openness to experience, gender, and type of student job influence the adoption. Subjects more open to experience, male, and working full time in the field they study use cryptocurrencies more.
