China occupies over 50% of total bitcoin mining output and ranks no. 1 in the number of tourists to Korea and casino visitors. When it comes to the recent Crypto-currency, casinos overseas already attempted to introduce crypto-currency due to the convenience associated with payment, safety, and quicker money exchange. Accordingly this study was conducted to understand more deeply the decision making process among users when Crypto-currency is introduced into casino. Casino is considered one of the fields in the tourism industry where Crypto-currency’s influence is expected in the future. Specifically using the TAM and TPB combined model. we aimed to identify the process of users’ decision making to use the casino that introduced the Crypto-currency. A total of 315 surveys from Chinese who had experience of visiting casino were used in this study. Data were analyzed using structural equation modeling. As a result of analysis, it appeared that among the variables that constituted the TAM and TPB combined model, individual’s perceived easiness and usefulness toward the casino that introduced the Crypto-currency had a significant impact, which eventually had an impact on the intention to use casino. It also appeared that perceived behavior control had a significant impact on the intention to use casino, but subjective norm did not have a significant impact on the intention to use casino. To successfully introduce Crypto-currency into casinos, there is a need to create an environment for anyone to easily and quickly use the casino. Furthermore establishing the infrastructure considering the subjectivity of users is also needed.
