The selection for this study is made through goal-directed selection, which is a selection of respondents who to some extent have knowledge of, or affected by, what the study intends to analyze. Conclusion: The conclusion indicates that millennials who have information about cryptocurrency in advance tend to experience more confidence in Bitcoin, as it is based on their information about the technology behind Bitcoin. Millennials also experience trust in Bitcoin according to their perception that it is not controlled by a third party; however, the cryptocurrency’s value depends on how it is liked by its investors or users. The respondents with a negative attitude were found to lack general information about the cryptocurrency and were, therefore, unwilling to accept the risks that accompany it. The respondents with a positive attitude proved to have confidence in the technology behind Bitcoin and, therefore, spread positive information about it by Word of Mouth.
