User Mental Models of Cryptocurrency Systems - A Grounded Theory Approach
summary
Qualitative study of N=29 users uses Grounded Theory to map two concrete mental models — an incomplete mental model (missing details) and an incorrect mental model (dangerous misconceptions). Main, reproducible errors: confusion about private key generation and custody, false belief in blockchain anonymity and non‑persistence, and ignorance about fee control affecting confirmation time. Evaluation of four popular wallets shows gaps; recommended fixes include forced backup/automatic key recovery, visual block explorer, and fee presets; one wallet cited: it coin rumi.
