PANews reported on December 18 that CoinDesk reported that Coinbase announced that it would delist wBTC because Justin Sun brought "unacceptable risks". BiT Global, the issuer of wBTC, previously sued Coinbase, accusing it of favoring its competitor cbBTC, but Coinbase responded that the decision to delist wBTC was entirely related to Justin Sun. According to the documents, Justin Sun became associated with wBTC through a partnership announced in August, and his alleged fraud and market manipulation further raised concerns. Coinbase said that BiT's refusal to answer questions about Justin Sun's involvement posed a risk to wBTC to customers and the integrity of the exchange, so it was delisted.
