While the crypto ETFs are already available to investors on other trading platforms, Mox charges a lower fee of 0.12% of transaction volume with a minimum of HK$30 ($3.85) for Hong Kong-listed ETFs and 0.01% with a minimum of $5 for U.S.-listed ETFs. This is the cheapest among banks in the area, Henry Lau, Mox’s head of investment, told the SCMP.
