论文摘要
加密货币已被广泛研究为基于区块链的分散金融技术。但是，缺乏对加密货币交换的用户体验的了解，这是新手用户与加密货币互动的主要手段。我们进行了定性研究，以提供对用户体验和交流安全感知的全景。所有15名中国参与者主要使用集中式交流（CEX）而不是分散的交流（DEX）来交易分散的加密货币，这是自相矛盾的。仔细检查表明，与DEXE相比，CEXE提供了更好的可用性和收费更低的交易费用。观察到国家特定的安全感。尽管Dexes提供了更好的匿名性和隐私保护，并且没有政府的监管，但对于许多参与者来说，这些不是必要的功能。根据发现，我们提出了设计含义，以使加密货币交易更加分散。
Cryptocurrency has been extensively studied as a decentralized financial technology built on blockchain. However, there is a lack of understanding of user experience with cryptocurrency exchanges, the main means for novice users to interact with cryptocurrency. We conduct a qualitative study to provide a panoramic view of user experience and security perception of exchanges. All 15 Chinese participants mainly use centralized exchanges (CEX) instead of decentralized exchanges (DEX) to trade decentralized cryptocurrency, which is paradoxical. A closer examination reveals that CEXes provide better usability and charge lower transaction fee than DEXes. Country-specific security perceptions are observed. Though DEXes provide better anonymity and privacy protection, and are free of governmental regulation, these are not necessary features for many participants. Based on the findings, we propose design implications to make cryptocurrency trading more decentralized.
