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.
Mom vloggers, stay-at-home moms streaming their daily life through short videos, suffer from both intensive motherhood and heavy digital work, yet receive little attention from researchers and designers. Toward understanding mom vloggers' motivations, practices, and challenges, we present exploratory results of an interview study (N=4) situated in China. Financial return, recording life and seeking agency/identity are found to be main motivators for mom vlogging. Revenues gained from advertising/selling products may make up for the decrease of income after leaving their paid employment, and together with the support and feedback from viewers, our participants' worth-based self-esteem is fulfilled. Typical challenges associated with mom vlogging include privacy leakage, invisibility of videos in early stage, and intensive digital work. Based on the findings, we propose design implications to accommodate the needs of mom vloggers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
