The topic of the thesis is the application of cryptocurrencies as a means of payment in tourism and catering. The aim of the research is to analyze the potential of cryptocurrencies as an alternative means of payment in tourism and to investigate how familiar users and providers of tourism services are with this technology. Special emphasis is placed on the advantages, challenges and user perception, along with an analysis of the economic and security dimensions of the use of cryptocurrencies. Cryptocurrencies, which have developed over the past decade thanks to blockchain technology, represent a significant innovation in financial business. Their decentralized nature enables the reduction of transaction costs, faster and safer payment, as well as greater user anonymity. However, the volatility of the value of cryptocurrencies and the lack of a clear regulatory framework pose challenges for their widespread implementation in tourism. The research is based on a quantitative method, and the data was collected through an online survey. 112 respondents participated in the survey, among whom the majority were younger users with a high level of awareness of cryptocurrencies. Despite this, the results showed that the actual use of cryptocurrencies is still relatively limited. The majority of respondents did not use cryptocurrencies to pay for tourism services, although they were aware of their advantages, especially in the context of international transactions. The survey also pointed to challenges in the adoption of cryptocurrencies, with respondents expressing concerns about the security of transactions and the complexity of use. Although blockchain technology provides a high level of security, the perception of the risk of fraud and the volatility of the value of cryptocurrencies is an obstacle to their wider adoption. Cryptocurrencies have the potential to enhance the image of tourist destinations as innovative and technologically advanced. The wider application of cryptocurrencies as a means of payment in tourism and hospitality depends on solving current challenges and the continuous digital transformation of the sector.
