Bitcoinsand was a Chinese‑initiated concept described as a “bitcoin bank.” It was associated with Wang Cong, who envisioned a deposit‑taking and inter‑user transfer service backed by a guarantor. Li Xiaolai was named as the guarantor for Bitcoinsand. Critics argued that its banking functionality was incomplete and that its profitability model differed from those of traditional banks.
