In this work, we attempt to discover traits that might improve the possibility of acceptance and ongoing usage of technology such as cryptocurrency adoption. More specifically, we focused on Rogers' Innovation Diffusion Theory (IDT, Theory of Technology Acceptance (TAT), and Technology Acceptance Model. (TAM)/TAM2/TAM3, Theory of Reasoned Action (TRA), Unified Theory of Acceptance and Use of Technology (UTAUT), and Theory of Planned Behaviour (TPB). When researching the tendency of individuals to adopt certain technologies, researchers draw from a wide variety of conceptual frameworks and analytical approaches. In this review, social psychology and its applied notions have been utilised most frequently. As a primary theoretical foundation, the theories centre on people's intentions to engage in a specific behaviour (i.e., adopt and utilise ICT), which is the emphasis of the theories. Research on the adoption and usage of information and communication technologies has made extensive use of both the Theory of Reasoned Action (TRA) and the Theory of Planned Behaviour (TPB). They are two of the key intention-based theories, which means they give the core theoretical underpinnings for other adoption theories, such as the Technology Acceptance Model (TAM) and the Enhanced Technology Acceptance Model. Both the transpersonal relationship analysis and the transpersonal behaviour analysis begin with the fundamental premise that individuals deliberately choose whether or not they will engage in a certain behaviour. In this sense, the adoption and usage intentions are typically seen of as a primary outcome variable that is influenced by a variety of independent variables. This is because of the way that they are typically studied. In the following, we will discuss significant theories regarding the adoption of technology.

Introduction The paper presents selected theories of technology acceptance in the light of cryptocurrency adoption. The term "adoption- diffusion theories" refers to the process that involves the gradual dissemination of an innovative idea over the course of time. The process of adoption relates to an individual deciding whether or not to integrate an innovation into their daily routine, whereas the process of diffusion takes on the adoption of an innovation by a group over a period of time. In the most recent decades, the rate of new scientific discoveries has quickened, and concurrently, the rate at which new technologies and inventions
