In the crypto, if exchanges only focus on transaction matching, their growth caps and casino-like positioning are very clear; essentially, they are no different from Las Vegas – a financial game. OKX's attempt to transform into an on-chain financial services gateway is a promising yet challenging path. It requires a robust compliance system, effective risk control and custody, verifiable transparency, a stable product experience, and trustworthy collaboration across multiple chains and countries. While short-term profits may not be as high as in a casino, in the long run, financial infrastructure is a grand undertaking for the entire industry.
