The Securities Commission of Malaysia has added cryptocurrency exchange Huobi to its investor alert list, according to a recent release.The primary reason for the move was because Singapore-based Huobi operates a digital asset exchange in the country without being registered with the securities regulator."In Malaysia, any parties that carry out capital market activities require the SC’s approval, even if they are approved to operate in other countries. Investors are strongly urged not to invest in any unlicensed or unregistered entities," SC Malaysia wrote in a Twitter post.In a follow-up Twitter post, SC Malaysia warned that Huobi's unregistered operations "put investors at risk" since the "SC's regulatory authority over them is limited."Huobi did not immediately respond to a request for comment by Seeking Alpha.At the beginning of August, Huobi registered with Australian financial watchdog.
