Research on virtual assets has been mainly interested in policy preparation or legislation for the introduction of virtual assets, or virtual asset operation technology, but this study presents investment factors that most asset investors consider important when making investment decisions. By doing so, we came up with research results that are practically helpful to virtual asset investors. According to the research results, (1) virtual asset investors consider business models such as marketability and competitive advantage of virtual assets as the most important factors, and (2) are highly interested in factors that can be objectively judged when investing in virtual assets. The results of this study suggest that a virtual asset trading market environment that can provide objective investment information and discover various judgment factors that enable virtual asset investors to objectively judge virtual assets should be prepared, and that virtual asset businesses using core technologies will continue to grow. This suggests that a variety of policy support is needed to enable this.

Since the advent of Bitcoin, various virtual assets have been actively traded through virtual asset services of virtual asset exchanges. Recently, security accidents have frequently occurred in virtual asset exchanges, so the government is obligated to obtain information security management system (ISMS) certification to strengthen information protection of virtual asset exchanges, and 56 additional specialized items have been established. In this paper, we compared the domain importance of ISMS and CryptoCurrency Security Standard (CCSS) which is a set of requirements for all information systems that make use of cryptocurrencies, and analyzed the results after mapping them to gain insight into the characteristics of each certification system. Improvements for 4 items of High Level were derived by classifying the priorities for improvement items into 3 stages: High, Medium, and Low. These results can provide priority for virtual asset and information system security, support method and systematic decision-making on improvement of certified items, and contribute to vitalization of virtual asset transactions by enhancing the reliability and safety of virtual asset services.

The purpose of this study is to provide an environment that can support the development of the virtual asset industry. The limiting factors and countermeasures currently possessed by the virtual asset industry were considered in terms of legal and institutional aspects, technical aspects, and market aspects.Small businesses classified as virtual asset operators have difficulty meeting the government's requirements.Accordingly, SMEs with insufficient funds and manpower are withdrawn from the market, creating an environment where only large-scale enterprises with capital power survive.It is difficult to develop desirable technologies and markets in the virtual asset technology industry. In addition, small and medium-sized companies may be expelled from the market, causing damage to current users. Therefore, in terms of legal and institutional aspects, there is a lack of an exact scope of virtual asset providers, and thus it is necessary to respond to the controversial elements of virtual asset providers. In terms of technology, it is necessary to cope with the slowdown of the P2P method, the difficulty in recovering errors, and the absence of operational experts. Therefore, technology standardization and stabilization are required, and efforts must be made to cultivate operational technical personnel who can support them.In terms of the market, it is necessary to prepare measures to protect users of virtual assets and to establish countermeasures for companies operating virtual assets against weak user protection, inadequate application of the AML method, and limitations of taxation. This study is expected to contribute to active utilization support or related policies in the virtual asset industry.

With the virtual asset market's rapid growth, government regulations on listing and trading procedures are expected. However, specific measures are currently lacking. To ensure stable inclusion in the institutional framework, precise regulations are needed for market development and investor protection. This study compares self-regulatory guidelines of the top domestic virtual asset exchanges with Korea Exchange's Preliminary Listing Examination Standards (2022) to enhance timeliness and relevance. It defines IEO, IPO, and ICO concepts and addresses conflicts of interest in IEO. Analyzing delisted virtual assets, it categorizes issues and classifies listing examination guidelines into formal and qualitative requirements. The study examines self-regulatory guidelines based on continuity, transparency, stability, corporate characteristics, and investor protection criteria, along with five special requirements for virtual assets. Improvement measures include regular disclosures of governance structure, circulation volume, and the establishment of independent audit institutions. This research further analyzes delisting cases, classifies issues, and proposes solutions. Considering stock market similarities, it offers measures based on the institutional framework.

최근 스캠 코인에 의한 피해 사례가 증가함에 따라 대부분의 가상자산 거래소가 상장된 가상자산에 대해 자체적 신뢰도 평가를 수행하고 있으나, 관련 법·제도적 체계의 부재로 인해 여전히 위험이 존재한다. 스캠 코인 여부를 판단하는 기존 서비스는 불명확한 스캠 코인 판별 기준으로 인해 충분히 신뢰하기 어려우며, 지도 학습에 필요한 라벨링 된 데이터셋이 충분하지 않아 관련 연구 또한 한계를 가진다. 본 논문은 클러스터링을 통해 스캠 코인 여부를 판단하는 것을 목표로 한다. 스캠 코인과 정상적인 가상자산을 구분하는 과정에서 유의미한 데이터를 수집하여 클러스터링을 수행하고, 스캠 코인 여부가 라벨링 된 테스트셋을 구성하여 클러스터링 결과를 평가한다. 이를 통해 본 논문이 제시하는 이더리움 기반 토큰에 대한 클러스터링 결과를 기반으로 추후 통일된 스캠 코인 판단 기준을 세울 수 있음을 제안한다.

The virtual world is a cyber gaming space where a player interacts with others through their avatars. It is now mainly developed in foreign countries including USA, Canada, and Europe and many experts say that the market capacity of virtual world will be continually expanded in worldwide. The virtual world will mostly be made such that a user accesses the world for free and pays for in-game activities. But it is hardly that we find the effective methodology of payment system for such virtual world due to its' short development history. In the case of Korea, various payment methods of selling in-game assets have been tested in online games. The paper propose an effective revenue model for social virtual world focused on selling in-game assets. The guideline of the proposed revenue model will be expected to contribute creating revenue focused on selling in-game assets, effectively for social virtual world.

Blockchain, which is the basis of virtual assets such as cryptocurrency, is receiving great attention as one of the cornerstone technologies of the 4th industrial revolution. Blockchain is a technology that can fundamentally change our lives not only in finance, but also in politics, logistics, and culture. However, it shows lower-than-expected usability because it is complicated to learn and is continuously being developed. In this study, we tried to investigate whether the Technology Acceptance Model(TAM) of virtual assets can be changed through education on the underlying technology, blockchain. A video-based online experiment was conducted with a total of 103 participants and examined how the type of training(positive, negative) and measurement timing(before, after) affect perceived usefulness, perceived ease of use, acceptance, which are TAM variables, and trust and security, which are related to blockchain characteristics. As a result of the experiment, interactions were found in all dependent variables according to the type of education and measurement timing. Specifically, groups that received negative education had no difference in all variables before and after, but it was found that groups that received positive education showed an increase afterwards. Through this, it can be seen that the effect of education based on the anchoring effect is also shown in the intention to use virtual assets using block chain technology, suggesting that the intention to use blockchain related technology can be increased through positive education.

Online game is the most popular representative example of the fast growing virtual world. Also, influence of interaction between virtual and real world is getting greater, and much discussion about virtual world and economy. However, it is often overlooked that the types of virtual economy can be very diverse depending on conditions of social and legal environment and policies of companies. Therefore, the influence of interactions between virtual world and real world is not managed by government and companies properly enough. We propose that virtual world is a system which has six types of agents and five types of transactions. Then there are twenty-four combinations, and we illustrated four typical combinations among them to explain practical applications of our model. The purpose of our categorization is not only to help to understand characteristics but also to provide insights for management and improvement for virtual worlds.
