Bitcoin adoption in online payments: examining consumer intentions and word-of-mouth recommendations

Online retailers in emerging markets like South Africa are adopting Bitcoin payments. This study explores factors driving consumer adoption and word-of-mouth (WOM) recommendations for Bitcoin in online transactions. Using an integrated model combining valency theory, social contagion theory, and the technology acceptance model (TAM), we analyse data from 521 South African online shoppers. Findings reveal that perceived usefulness, ease of use, social pressures, trust, and perceived risk significantly influence both adoption and WOM. Importantly, self-efficacy moderates the relationship between these factors and behaviour. This research contributes to the literature by offering a comprehensive understanding of Bitcoin adoption. For business and policy actors, enhancing consumer self-efficacy can foster trust, ease concerns, and encourage positive WOM, ultimately aiding successful Bitcoin implementation and promotion.
