ZA Bank, Hong Kong's largest digital bank, has initiated Bitcoin and Ethereum trading for retail customers through a collaboration with licensed crypto exchange HashKey. This move marks a significant step in integrating traditional banking with cryptocurrency trading, reflecting a growing trend among financial institutions. However, the broader market remains fraught with uncertainty as regulatory pressures intensify globally. The introduction of such services could face significant challenges if regulatory frameworks tighten, potentially impacting the adoption and growth of digital currencies in traditional banking sectors.
