According to CoinMeta, Jiang Zhuoer, the founder of Leibit Mining Pool, stated that after the recent decline in Bitcoin prices, the premium for Bitcoin of Coinbase remains negative, and the extent of this negative premium has expanded. It is expected that there may be a net outflow of US spot BTC ETF on the next trading day. He also pointed out that there is a certain lag in the data on ETF capital flows. Trading based solely on the already published ETF data is akin to "driving while looking in the rearview mirror." However, since ETF capital flows have a significant impact on the market, they still hold important reference value.
