Kraken Downgraded to B-Tier by ZachXBT Over Token Listings and Breach Response

ZachXBT, a prominent figure in the cryptocurrency community, has downgraded Kraken to B-tier from S-tier in his centralized exchange ranking. This decision comes after ZachXBT escalated criticism around exchange listings for tokens he described as low-quality or manipulated.

The tokens in question include MemeCore M, Rain, RaveDAO, and River, which are currently supported by Kraken across its platform. The move is notable because Kraken has long been viewed as one of crypto's stronger security-first exchanges.

ZachXBT's criticism centers on due diligence, arguing that major exchanges should not treat every trending token as listing-ready. He emphasizes the importance of reviewing tokens for signs of manipulation, weak product traction, opaque team links, and concentrated supply.
