Web3 asset data platform RootData released the seventh issue of the "Cryptocurrency Exchange Transparency Ranking (Stock Category)", continuing to focus on the growth trend of stock assets in cryptocurrency exchanges. In this issue, Binance, OKX, Bybit, Bitget, and Gate ranked in the top five.Among them, Bybit's ranking improved by 2 places, re-entering the top three, mainly due to Bybit listing 49 new stock contracts during the statistical period, making it the exchange with the most supported stocks currently. Bitget's ranking dropped by 2 places, with traffic decreasing by over 40%, which may be related to the rapid decline in traffic following the end of the SPAX subscription activity.As the market prices of cryptocurrencies like Bitcoin rise, the trading volume of exchanges generally increased by over 10% in this issue, with Kraken rising by over 20%, boosting its ranking to 6th place. Hotcoin, on the other hand, fell to 10th place due to a decrease in its transparency score.It is reported that RootData adheres to the principle of "transparency first" and has taken the lead in establishing a dual evaluation system of "transparency + liquidity" in the field of stock cryptocurrency exchanges, providing investors with more effective data references, and will continue to enhance and publish this ranking in the future.

The Bank for International Settlements (BIS) released a report indicating that cryptocurrency exchanges are gradually providing bank-like services, such as lending and earn products, but lack the regulation and deposit protection found in traditional financial systems, posing systemic risks.The report states that these high-yield products are essentially closer to "unsecured loans," where user assets are often used by the platform for high-risk operations such as lending, trading, or market making, and users only hold a creditor position against the platform. If the platform encounters problems, users will be directly exposed to repayment risks. The BIS also noted that leading cryptocurrency platforms have evolved from single exchanges into "multi-functional intermediaries," integrating the functions of banks, brokerages, and exchanges, but lacking transparency and risk isolation mechanisms. The previous collapses of Celsius Network and FTX are typical cases of such structural risks. Additionally, the report mentioned that the flash crash in the cryptocurrency market in October 2025 triggered approximately $19 billion in forced liquidations, highlighting the chain reaction risks under high leverage and opaque structures.
