The claim is well supported by corroborating reports that specifically attribute the information to the Business Wire announcement. The PANews article says COINSOV '按反向波动率动态调整Bitcoin与黄金权重,并按季度再平衡,' directly matching the statement's 'rules-based allocation' tied to volatility and quarterly rebalancing. The crypto.news article independently describes COINSOV as using an 'inverse volatility weighting model' and says it 'rebalances quarterly.' The original Business Wire URL was traced from the Odaily link, which strengthens provenance, but because the direct fetch of the Business Wire page failed, the primary-source wording could not be validated firsthand in this run. That limits confidence slightly, but the available evidence strongly supports the statement.
